This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value.
In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.

Per-light energy gives more control to the user on the final result of
volumetric fog. Specific lights can be fully excluded from volumetric fog
by setting their volumetric fog energy to 0, which improves performance
slightly. This can also be used to prevent short-lived dynamic effects
from poorly interacting with volumetric fog, as it's updated over several
frames by default unless temporal reprojection is disabled.
Volumetric fog shadows now obey Light3D's Shadow Opacity property as well.
The shadow fog fade property was removed as it had little visible impact
on the final scene's rendering.

Implementation of Octahedral normal compression into Godot 4.0

This can be used to make shadows translucent for a specific light.
The light distance fade system also uses this to smoothly fade the shadow
when the light fade transition distance is greater than 0.

`shader_uniform` is now consistenly used across both per-shader
and per-instance shader uniform methods. This makes methods easier
to find in the class reference when looking for them.
|
|
This is consistent with the BaseMaterial3D filtering options.
It can be used for high-quality pixel art textures that remain sharp
when viewed at oblique angles, but prevents them from becoming grainy
thanks to mipmaps.

The `global_shader_uniform` name is longer, but it makes it much
easier to find the methods when searching in the class reference.

Mipmap LOD bias can be useful to improve the appearance of distant
textures without increasing anisotropic filtering (or in situations
where anisotropic filtering is not effective).
`fsr_mipmap_bias` was renamed to `texture_mipmap_bias` accordingly.
The property hint now allows for greater precision as well.
|
|
The former needs to be allocated once per usage. The later is shared for all threads, which is more efficient.
It can also be better debugged.

* Moved preprocessor to Shader and ShaderInclude
* Clean up RenderingServer side
* Preprocessor is separate from parser now, but it emits tokens with include location hints.
* Improved ShaderEditor validation code
* Added include file code completion
* Added notification for all files affected by a broken include.

Improve GI renderer and add VRS support
Implement render device has_feature and move subgroup settings to limit_get

`rendering/quality/shadows` is now `rendering/quality/positional_shadow`
to explicitly denote that the settings only affect positional light shadows,
not directional light shadows.
Shadow atlas settings now contain the word "atlas" for easier searching.
Soft shadow quality settings were renamed to contain the word "filter".
This makes the settings appear when searching for "filter" in the
project settings dialog, like in Godot 3.x.

This allows for previewing the effects of the various 3D scaling
project settings without having to restart the editor.

Initial TAA support based on the implementation in Spartan Engine.
Motion vectors are correctly generated for camera and mesh movement, but there is no support for other things like particles or skeleton deformations.

This complements the existing Ellipsoid and Box local fog shapes.
This can be used to represent a light cone coming from a SpotLight.

With FSR 2.0 around the corner, we should avoid any ambiguity by
explicitly stating the version number.

This method can be used to get the graphics API version currently in
use (such as Vulkan). It can be used by projects for troubleshooting
or statistical purposes.

This shadow color property was no longer effective since the shaders
were optimized to improve occupancy.

This can be used to fade lights and their shadows in the distance,
similar to Decal nodes. This can bring significant performance
improvements, especially for lights with shadows enabled and when
using higher-than-default shadow quality settings.
While lights can be smoothly faded out over distance, shadows are
currently "all or nothing" since per-light shadow color is no longer
customizable in the Vulkan renderer. This may result in noticeable
pop-in when leaving the shadow cutoff distance, but depending on the
scene, it may not always be that noticeable.

Remove currently unused implementation of TextureBasisU, could be re-added
later on if needed and ported.

This provides a significant speedup for a small quality loss.
The quality loss is generally more noticeable during a project's
early stages of development (e.g. in level blockouts)
than it is in a finished project.
