- Adds Swappy for Android for stable frame pacing
- Implements pre-transformed Swapchain so that Godot's compositor is in
charge of rotating the screen instead of Android's compositor
(performance optimization for phones that don't have HW rotator)
============================
The work was performed by collaboration of TheForge and Google. I am
merely splitting it up into smaller PRs and cleaning it up.
Changes from original PR:
- Removed "display/window/frame_pacing/android/target_frame_rate" option
to use Engine::get_max_fps instead.
- Target framerate can be changed at runtime using Engine::set_max_fps.
- Swappy is enabled by default.
- Added documentation.
- enable_auto_swap setting is replaced with swappy_mode.
The `env.disabled_modules` and `methods.disable_module` weren't used anywhere
so the first one was repurposed and the second just deleted

Adds an optional (default false) compile option to enable comparing
`Ref` to `nullptr` to ensure correct use, as well as future expandsion
for more general dev checks (enabled with `dev_mode`)
Prevents cache issues by not purging cache before starting a build.
Splits cache purge related code from progress code and delays the purge
until after final build is done.
After upgrading, I noticed that the SCons ninja output had a different
filename which messed up the "flaky file" logic.
This patch explicitly passes it to the tool and switches to
`build.ninja` (ninja's default).
The `-j` flag is only settable via the command line, which makes it hard
to configure when running builds from places like VS, where the flag isn't
easily exposed or configurable.
This lets users configure the number of jobs to be used by default if `-j`
isn't specified, instead of always defaulting to number of cores - 1.

Some of the logic in SCons depends on flags that get overridden in the
platform-specific `detect.py`, so it needs to be processed first.
For example the Android/iOS/Web platforms override the default `target`
to `template_debug`, but this was processed too late so e.g. the logic
that sets `env.editor_build` would set it to true due to the default
`target` value in the environment being `editor`.
The min SCons version had to be bumped as SCons 3.0 before 3.0.3 seems
broken (see #92043), and there's little gain from supporting 3.0.3-3.0.5.
3.1.2 is also the first version to avoid ambiguities between Python 2
and Python 3 usage, so we finally use it as the minimum baseline.
Also test against Python 3.6 which is also our minimum supported version.
This should help prevent regressions whenever we modernize the build scripts.
