Only emit the JavaScript support code for Web when building for HTML5
Excluding other unused environments like Node.js makes the support code

4a50f5ff65 HTML5 callbacks rework.
Fixes compatibility with emscripten 1.39.5+ .
Most input callbacks now require a target and no longer support NULL
defaults.

This commit changes all required null targets to the expected default in
the binding phase.
Since for canvas-related callbacks there is no default, the "#canvas"
selector is used instead.
Additionally, since canvasX and canvasY event properties are no longer
supported, event positions are computed from "clientX" and "clientY" and
the "#canvas" bounding client rect.

435f86cf87 HTML5: Address removal of 'timestamp' in Emscripten 1.39.5
It was removed as noted in the changelog:
https://github.com/emscripten-core/emscripten/blob/1.39.5/ChangeLog.md#v1395-12202019

> Removed `timestamp` field from mouse, wheel, devicemotion and
> deviceorientation events. The presence of a `timestamp` on these
> events was slightly arbitrary, and populating this field caused
> a small profileable overhead that all users might not care about.
> It is easy to get a timestamp of an event by calling
> `emscripten_get_now()` or `emscripten_performance_now()` inside
> the event handler function of any event.

Fixes #34648.

5011afcb6a Export: Improve usability of command line interface
I'm barely scratching the surface of the changes needed to make the
--export command line interface easy to use, but this should already
improve things somewhat.

- Streamline `can_export()` templates check in all platforms, checking
  first for the presence of official templates, then of any defined
  custom template, and reporting on the absence of any.
  Shouldn't change the actual return value much which is still true if
  either release or debug is usable - we might want to change that
  eventually and better validate against the requested target.

- Fix discrepancy between platforms using `custom_package/debug` and
  `custom_template/debug` (resp. `release`).
  All now use `custom_template`, which will break compatibility for
  `export_presets.cfg` with earlier projects (but is easy to fix).

- Use `can_export()` when attempting a command line export and report
  the same errors that would be shown in the editor.

- Improve error reporting after a failed export attempt, handling
  missing template and invalid path more gracefully.

- Cleanup of unused stuff in EditorNode around the export workflow.

- Improve --export documentation in --help a bit.

Fixes #16949 (at least many of the misunderstandings listed there).
Fixes #18470.

6d6280dfa3 Emscripten: Re-add BINARYEN_TRAP_MODE='clamp' for fastcomp
The option is needed when using the 'fastcomp' backend (default before
1.39.0), and must not be defined when using 'upstream' (new default).
So we define it conditionally to support both backends.

02913f53d3 pcre2: Use scons option to disable JIT on some platforms

e5dfcb5edd HTML5: Explicitly link idbfs.js for IDBFS support
Upstream Emscripten changed this in 1.39.1+, so IDBFS is no longer
included by default and has to be linked manually.

The explicit linking doesn't seem to be problematic on earlier
versions (tested `1.38.47-upstream`).

e9e2a4b044 HTML5: Fix support for Emscripten 1.39.1+
A change in upstream Emscripten 1.39.1+ made our buildsystem error
out where it was previously only issuing a warning:
```
[  5%] Linking Static Library ==> main/libmain.javascript.opt.bc
shared:WARNING: Assuming object file output in the absence of `-c`, based on output filename. Please add with `-c` or `-r` to avoid this warning
Ranlib Library         ==> main/libmain.javascript.opt.bc
/opt/emsdk/upstream/bin/llvm-ranlib: error: unable to load 'main/libmain.javascript.opt.bc': file too small to be an archive
```

As advised on emscripten-core/emscripten#9806, we should be using
`emar` here to create the static library and not `emcc`.
This was apparently done to workaround Emscripten issues in the past,
but evidently this is no longer necessary.

The rest of the `env` redefinitions should probably be re-assessed
against the current state of Emscripten.

Fixes #33374.

0c19674621 Better detect Emscripten toolchain.
Emscripten is apparently changing the variables in its config file,
causing potential breakage of our build system.

Binaries of the latest/latest-upstream releases are located in a
subfolder of BINARYEN_ROOT called emscripten.
Binaries of the other releases (e.g. sdk-1.38.31-64bit) are instead
placed under the EMSCRIPTEN_ROOT folder.

This PR checks if BINARYEN_ROOT has a subfolder called emscripten, if
that does not exists, it falls back to checking the EMSCRIPTEN_ROOT.

This way we give precedence to the new releases, given that activating
multiple releases sequentially might result in having mismatching
BINARYEN_ROOT and EMSCRIPTEN_ROOT.

Fix Emscripten root directory detection when building for HTML5

2b436dd50e Kinda working HTML5 clipboard paste.
Listen to paste events to update local clipboard.
CTRL+V still not working out of the box.
To do that, We would need to change how we handle keypress, most likely
making it worse and less safe. In the end, I'm not sure we can fix it
properly for now. Maybe in the future, with the Clipboard API, support
of which is still pretty limited on chrome, and only available to
extensions in Firefox.

For now, you can paste via:
- Browser bar -> Edit -> Paste.
- Middle mouse click (Linux only, copies secondary clipboard).

And THEN press CTRL+V

b0f782a0e3 Disable driver fallback to GLES2 by default
GLES2 is not designed to be a drop-in replacement for the GLES3 backend,
so the fallback mode has to be used knowingly. It *can* make sense for
simple projects which make sure to handle the differences between both
rendering backends, but most users should stick to one supported backend.

By making it opt-in, we can now use this parameter to define whether to
export ETC textures to Android and iOS when using GLES3 + Fallback.

When using GLES3 without Fallback on Android, set the proper min GLES
version in the AndroidManifest.

Also made the option boolean and renamed it for clarity and to avoid
conflict with the previous String option (which would always evaluate as
"true" otherwise).

277b24dfb7 Make core/ includes absolute, remove subfolders from include path
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.

08f452d1a9 Fall back to GLES2 if GLES3 is not working
This adds a static is_viable() method to all rasterizers which has to be
called before initializing the rasterizer. This allows us to check what
rasterizer to use in OS::initialize together with the GL context
initialization.

This commit also adds a new project setting
"rendering/quality/driver/driver_fallback" which allows the creator of a
project to specify whether or not fallback to GLES2 is allowed. This
setting is ignored for the editor so the editor will always open even if
the project itself cannot run. This will hopefully reduce confusion for
users downloading projects from the internet.

We also no longer crash when GLES3 is not functioning on a platform.

This fixes #15324
