dcb68e0106 SCons: Improve registration of compilation_db tool, check version
There's a builtin `toolpath` option we can use for that, so no need to hack
around a custom `scons_site` path.

The script requires SCons 3.1.1 or later, so we enable it conditionally.

Follow-up to #32848.

9aa4648579 Added compilation database support for clang and gcc
This tool is originally from mongodb.

- Updated CPPSUFFIXES to use scons suffixes
- objective-c files will also be loaded into the compilation database where the compiler / tooling is available to compile the files.

Known limitations:

- This will not work with msvc as your compiler.

98d0bf7d7a assimp: Clean and document buildsystem, prepare for unbundling
- Improve the SCsub to allow unbundling and remove unnecessary code.
- Move files around to match upstream source.
- Re-sync with upstream commit 308db73d0b3c2d1870cd3e465eaa283692a4cf23
  to ensure we don't have local modifications.
- Doesn't actually build against current version 5.0.1 due to the lack
  of the new ArmaturePopulate API that Gordon authored. We'll have to
  wait for a public release with that API (5.1?) to enable unbundling.

c34b351b24 SCons: Explicitly define our C (C11) and C++ (C++14) standards
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.

c320a82213 SCons: Add 'split_libmodules' option to workaround linker issue
The new 'split_libmodules=yes' option is useful to work around linker
command line size limitations when linking a huge number of objects.
We're currently over 64k chars when linking libmodules.a on Windows
with MinGW, which triggers issues as seen in #30892.

Even on Linux, we can also reach linker command line size limitations
by adding more custom modules.

We force this option to True for MinGW on Windows, which fixes #30892.

Additional changes to lib splitting:

- Fix linking of the split module libs with interdependent symbols,
  hacking our way into LINKCOM and SHLINKCOM to set the `--start-group`
  and `--end-group` flags.
- Fix Python 3 compatibility in `methods.split_lib()`.
- Drop seemingly obsolete condition for 'msys' on 'posix'.
- Drop the unnecessary 'split_drivers' as the drivers lib is no longer
  too big since we moved all thirdparty builds to modules.

02913f53d3 pcre2: Use scons option to disable JIT on some platforms
Third-party platforms (e.g. console ports) need to be able to
disable JIT support in the regex module too, so it can't be
hardcoded in the module SCsub. This is cleaner this way anyway.

Fixes #19316.

5dae2ea777 SCons: Enable C++11 on the whole codebase
**Important:** This does not mean *yet* that C++11 features should be used
in contributions to Godot's codebase.

For now this change is done solely for feature branches working on Vulkan
support and GDScript typed instruction sets for Godot 4.0, which will both
use C++11 features and are based on the master branch.

The plan is to start porting the codebase to C++11 after Godot 3.2 is
released, following upcoming guidelines on the subset of new features that
should be used, and when/how to use them.

We will advertise clearly when C++11 contributions are open, especially
once we start a coordinated effort to port Godot's massive codebase. In the
meantime, please bear with us and good ol' C++03. :)

7c11a1b162 Add support for creating editor icons per module
The functionality is similar to how `doc_classes` are retrieved per module.
The build system will search for custom icons path defined per module via
`get_icons_path()` method in `config.py` or default icons path.
If such paths don't exist, only the editor's own icons will be built.

Most module icons were moved from editor/icons to respective modules.

beb34a0458 SCons: Enable -Werror and -Wextra in 'dev' build option
We're close to being able to compile all platforms with -Werror -Wextra,
so it's best if developers use those options when compiling their code
as those checks are also done on CI.

Also enabled -Wduplicated-branches on GCC.

c2a669a9f0 SCons: Review uses of CCFLAGS, CXXFLAGS and CPPFLAGS
Many contributors (me included) did not fully understand what CCFLAGS,
CXXFLAGS and CPPFLAGS refer to exactly, and were thus not using them
in the way they are intended to be.

As per the SCons manual: https://www.scons.org/doc/HTML/scons-user/apa.html

- CCFLAGS: General options that are passed to the C and C++ compilers.
- CFLAGS: General options that are passed to the C compiler (C only;
  not C++).
- CXXFLAGS: General options that are passed to the C++ compiler. By
  default, this includes the value of $CCFLAGS, so that setting
  $CCFLAGS affects both C and C++ compilation.
- CPPFLAGS: User-specified C preprocessor options. These will be
  included in any command that uses the C preprocessor, including not
  just compilation of C and C++ source files [...], but also [...]
  Fortran [...] and [...] assembly language source file[s].

TL;DR: Compiler options go to CCFLAGS, unless they must be restricted
to either C (CFLAGS) or C++ (CXXFLAGS). Preprocessor defines go to
CPPFLAGS.

fc370b3feb Fix -Wimplicit-fallthrough warnings from GCC 8
Adds `FALLTHROUGH` macro to specify when a fallthrough is intentional.
Can be replaced by `[[fallthrough]]` if/when we switch to C++17.

The warning is now enabled by default for GCC on `extra` warnings level
(part of GCC's `-Wextra`). It's not enabled in Clang's `-Wextra` yet,
but we could enable it manually once we switch to C++11. There's no
equivalent feature in MSVC for now.

Fixes #26135.
