- 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.
- Implements asynchronous transfer queues from PR #87590.
- Adds ubershaders that can run with specialization constants specified as push constants.
- Pipelines with specialization constants can compile in the background.
- Added monitoring for pipeline compilations.
- Materials and shaders can now be created asynchronously on background threads.
- Meshes that are loaded on background threads can also compile pipelines as part of the loading process.
This adds support in all backends, but the Compatibility renderer works the best.
Mobile and Forward+ can only support one directional light shader (the first in the tree)
While the Compatibility renderer supports any number of shadows.

This improves shadow quality by reducing the visibility of the noisy
pattern caused by dithering.
This jittering also applies when FSR2 is enabled, as it provides its own
form of temporal antialiasing.

If the module is enabled (default), 2D physics works as it did before.
If the module is disabled and no other 2D physics server is registered
(via a module or GDExtension), then we fall back to a dummy
implementation which effectively disables 2D physics functionality (and
a warning is printed).
The dummy 2D physics server can also be selected explicitly, in which
case no warning is printed.
We shall not leave the viewport transform to be rounded by the code for
rounding canvas items. Since the viewport transform is inverse to the
camera transform, we get incorrect rounding at the halfway point that
misaligns the viewport and the canvas item which the camera is
following.
Instead, reintroduce viewport rounding, but do it in a way that matches
the rounding of canvas items. Also take into account the half-pixel
offset of the centre point when viewport dimension is not divisible by
two. For `CanvasLayer`s that follows viewport, take into account the
scale when rounding. Overall this should work better compared to the
rounding in Godot 4.2 (and earlier).
