Adds fixed timestep interpolation to the rendering server (2D only).
Switchable on and off with a project setting (default is off).

This small in-engine documentation change aims to make it easier to
discover ways to handle pixel art aesthetics.
- I have moved 2D pixel snapping settings out of "Advanced." This now matches other pixel-art-friendly settings for
GUI Snapping and Default Texture filtering.
- I've added notes to the project settings and Sprite/AnimatedSprite sources to hint users towards better understanding of why pixelated sprites may not work correctly and what to do about it. This should help users make informed decisions for their needs.
Context: Proper handling of pixel art in Godot is routinely frustrating for new users: I, like others, assumed that Godot would act on pixels, not subpixels, when I was working a pixel art game. I was confused when my interpolations would appear blurry, and when pixel textures would be distorted for no apparent reason (this was because of centering).
I had naively thought that setting Linear interpolation would be the single "it's a pixel art game" toggle, but that only hid the underlying issues until later. I had no idea there was a snap-to-pixel option because it was hidden in the Advanced options, since my default assumption was that a pixel art game would want no subpixels at all.

Previously the `p_reversed` parameter didn't influence the order
in a correct way.
Also script overridden _notification functions were not called in
the correct order.
To fix this some `notification` functions had to add a `p_reversed`
parameter.
This made it necessary to adjust cpp-bindings.

This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance
Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.
SceneTree overrides the virtual `process` and `physics_process` methods
that it inherits from MainLoop. These methods return a boolean that
determines if the main loop should end.
The SceneTree was ignoring the returned boolean, so scripts inheriting
from SceneTree that override these methods and return true didn't exit
the main loop. Now the boolean is checked.
* Node processing works on the concept of process groups.
* A node group can be inherited, run on main thread, or a sub-thread.
* Groups can be ordered.
* Process priority is now present for physics.
This is the first steps towards implementing https://github.com/godotengine/godot-proposals/issues/6424.
No threading or thread guards exist yet in most of the scene code other than Node. That will have to be added later.
Provides an obvious way to unload the currently loaded scene (which is nowhere to be found in the docs).
The SceneTree.change_scene_to() method must now always provide a valid PackedScene.
Fixes#63565.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
