Facilitate exposing platform-exclusive interfaces to all platforms This makes the interfaces available, without implementation, in other platforms and the editor, which facilitates documenting platform-exclusive classes. Platform-exclusive APIs must be set up in platform/<platform>/api/api.cpp. Provide noop method-implementations where necessary. Also setup and document the HTML5 platform's JavaScript singleton.

SCons: unify code generations routine and minimize timestamp changes Previously, all of the code generation routines would just needlessly write the same files over and over, even when not needed. This became a problem with the advent of the experimental ninja backend for SCons, which can be trivially enabled with a few lines of code and relies on timestamp changes, making it thus impractical.

import methods
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.

Import("env")
SCons: Fix uses of [].append instead of env.add_source_files() Also added support for SCons project-absolute paths (starting with #) and warning about duplicates in add_source_files(), and fixed default_controller_mappings.gen.cpp being included twice after first build due to *.cpp globbing. Part of #30270.

Running builder (content generator) functions in subprocesses on Windows - Refactored all builder (make_*) functions into separate Python modules along to the build tree - Introduced utility function to wrap all invocations on Windows, but does not change it elsewhere - Introduced stub to use the builders module as a stand alone script and invoke a selected function There is a problem with file handles related to writing generated content (*.gen.h and *.gen.cpp) on Windows, which randomly causes a SHARING VIOLATION error to the compiler resulting in flaky builds. Running all such content generators in a new subprocess instead of directly inside the build script works around the issue. Yes, I tried the multiprocessing module. It did not work due to conflict with SCons on cPickle. Suggested workaround did not fully work either. Using the run_in_subprocess wrapper on osx and x11 platforms as well for consistency. In case of running a cross-compilation on Windows they would still be used, but likely it will not happen in practice. What counts is that the build itself is running on which platform, not the target platform. Some generated files are written directly in an SConstruct or SCsub file, before the parallel build starts. They don't need to be written in a subprocess, apparently, so I left them as is.
