SCons: Fix build with p alias or platform auto-detection
Fixes a pre-existing bug that #44433 exposed.

It's pretty hacky, but we use `platform` in `env` both as an optional command
line option (instead it can be autodetected, or passed via the `p` alias, and
on Linux it might be overridden if you pass one of the convenience alias
values), and as the reference value for what platform we're building on.

Thus we override `env_base["platform"]` with the autodetected or validated
platform, but any call to `opts.Update(env_base)` overrides it with the
original command line option... causing e.g. #44448.

The proper fix would be to refactor all this so that we don't reuse
`env["platform"]` for platform detection (it could instead be e.g.
`env.platform` as a member variable which holds the validated value),
but for now I'm tapering over the immediate breakage.

Fixes #44448 and other breakages induced by #44433.

SCons: Add only selected platform's opts to env
Otherwise we can get situations where platform-specific opts with the same name
can override each other depending on the order at which platforms are parsed,
as was the case with `use_static_cpp` in Linux/Windows.

Fixes #44304.

This also has the added benefit that the `scons --help` output will now only
include the options which are relevant for the selected (or detected) platform.

33b2070d2e Remove obsolete GLES2 backend code
This code currently isn't compiled (and cannot compile).

We plan to re-add OpenGL ES-based renderer(s) in Godot 4.0 alongside Vulkan
(probably ES 3.0, possibly also a low-end ES 2.0), but the code will be quite
different so it's not relevant to keep this old Godot 3.2 code.

The `drivers/gles2` code from the `3.2` branch can be used as a reference for
a potential new implementation.

d86de6c98e SCons: Refactor running commands through builders
A new `env.Run` method is added which allows to control the verbosity
of builders output automatically depending on whether the "verbose"
option is set. It also allows to optionally run any SCons commands in a
subprocess using the existing `run_in_subprocess` method, unifying
the interface. `Action` objects wrap all builder functions to include a
short build message associated with any action.

Notably, this removes quite verbose output generated by `make_doc_header`
and `make_editor_icons_action` builders.

579342810f t Add unit testing to Godot using DocTest and added to GitHub Actions CI
Implements exit codes into the engine so tests can return their statuses.
Ideally we don't do this, and we use FIXUP logic to 'begin' and 'end' the engine execution for tests specifically.

Since realistically we're initialising the engine here we don't want to do that, since String should not require an engine startup to test a single header.

This lowers the complexity of running the unit tests and even for
physics should be possible to implement such a fix.

8391ec256d SCons: Do not enable werror=yes by default
There are too many users who compile Godot from source and are not familiar
with the buildsystem or C/C++ compilation warnings, and thus report any kind
of yet-unfixed warning as a (often duplicate) bug.

Compiler warnings change at every compiler version and are different for each
compiler, so it's difficult to ensure that the codebase would always be 100%
warning-free, especially in the future.

I already disabled it for stable releases in #37958, but having it on non
stable commits could also become an annoyance in the future when trying to
bisect issues with a new compiler version which emits warnings unknown at
the time of commit.

TL;DR: Contributors, use `dev=yes` or `werror=yes`. CI does and won't let you
create new warnings ;)

5afe8cd782 SCons: Prefer Exit() method over sys.exit()
Sconscript provides it's own `Exit()` method which is currently
an alias for `sys.exit()` internally, with the only difference that if
no exit code is specified, it defaults to 0.

This encourages the usage of SCons-implemented methods like
`Glob()` over `glob.glob()`, which may overcome limitations of the
built-in Python features in the future.

17938fd547 SCons: use OrderedDict to ensure insertion order of modules
The insertion order for dictionaries is only a language feature for
Python 3.6/3.7+ implementations, and not prior to that.

This ensures that the engine won't be rebuilt if the order of detected
modules changes in any way, as the `OrderedDict` should guarantee
inerstion order.

a96f0e98d7 Add custom_modules build option to compile external user modules
This patch adds ability to include external, user-defined C++ modules
to be compiled as part of Godot via `custom_modules` build option
which can be passed to `scons`.

```
scons platform=x11 tools=yes custom_modules="../project/modules"
```

Features:

- detects all available modules under `custom_modules` directory the
same way as it does for built-in modules (not recursive);
- works with both relative and absolute paths on the filesystem;
- multiple search paths can be specified as a comma-separated list.

Module custom documentation and editor icons collection and generation
process is adapted to work with absolute paths needed by such modules.

Also fixed doctool bug mixing absolute and relative paths respectively.

Implementation details:

- `env.module_list` is a dictionary now, which holds both module name as
  key and either a relative or absolute path to a module as a value.
- `methods.detect_modules` is run twice: once for built-in modules, and
  second for external modules, all combined later.
- `methods.detect_modules` was not doing what it says on the tin. It is
  split into `detect_modules` which collects a list of available modules
  and `write_modules` which generates `register_types` sources for each.
- whether a module is built-in or external is distinguished by relative
  or absolute paths respectively. `custom_modules` scons converter
  ensures that the path is absolute even if relative path is supplied,
  including expanding user paths and symbolic links.
- treats the parent directory as if it was Godot's base directory, so
  that there's no need to change include paths in cases where custom
  modules are included as dependencies in other modules.

26ab805c78 SCons: Disable -Werror on 'stable' releases
Stable releases are tagged and need to stay easy to compile in the future.
As new compiler versions introduce new warnings or catch more occurrences,
have -Werror set in tagged releases could be a bother.

We still want it on by default for all Godot developers, so it's now
conditional.

cd4e46ee65 SCons: Format buildsystem files with psf/black
Configured for a max line length of 120 characters.

psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:

- Manually wrapped strings will be reflowed, so by using a line length
  of 120 for the sake of preserving readability for our long command
  calls, it also means that some manually wrapped strings are back on
  the same line and should be manually merged again.

- Code generators using string concatenation extensively look awful,
  since black puts each operand on a single line. We need to refactor
  these generators to use more pythonic string formatting, for which
  many options are available (`%`, `format` or f-strings).

- CI checks and a pre-commit hook will be added to ensure that future
  buildsystem changes are well-formatted.

a4801674c5 SCons: Bump required C++ standard to C++17
As per #36436, we now need C++17's guaranteed copy elision feature to
solve ambiguities in Variant.

Core developers discussed the idea to move from C++14 to C++17 as our
minimum required C++ standard, and all agreed. Note that this doesn't
mean that Godot is going to be written in "modern C++", but we'll use
modern features where they make sense to simplify our "C with classes"
codebase. Apart from new code written recently, most of the codebase
still has to be ported to use newer features where relevant.

Proper support for C++17 means that we need recent compiler versions:

 - GCC 7+
 - Clang 6+
 - VS 2017 15.7+

Additionally, C++17's `std::shared_mutex` (conditionally used by
`vk_mem_alloc.h` when C++17 support is enabled) is only available in
macOS 10.12+, so we increase our minimum supported version.

On GCC and Clang, we use C11 and C++14 with GNU extensions (`std=gnu11`
and `std=gnu++14`). Those are the defaults for current GCC and Clang,
and also match the feature sets we want to use in Godot.

On MSVC, we require C++14 support explicitly with `/std:c++14`, and
make it strict with the use of `/permissive-` (so features of C++17 or
later can't be used).

Moves the definition before querying environment flags and platform
config so that it can be overridden when necessary.
