Can't stop, won't stop, they said, huh?

385ee5c70b Implement Physical Light Units as an optional setting.
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.

Add dithering to ProceduralSkyMaterial to combat banding
Dithering was already present in PhysicalSkyMaterial. This brings
it to ProceduralSkyMaterial as well, with the same algorithm
and default intensity.

Add an XML schema for documentation
This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.

Each class XML's schema conformance is also checked on GitHub Actions.

Add sky cover texture for ProceduralSkyMaterial
This brings PhysicalSkyMaterial's Night Sky functionality to
ProceduralSkyMaterial, but in a more powerful and general fashion.

This can be used to display stars at night, or clouds at day and night.
For clouds, it won't be physically accurate, but it can look good still.

The Sky Cover Modulate property can be used to adjust the sky cover's
colors and opacity in real-time, which is useful for day/night or weather
transitions.

Tweak default ProceduralSkyMaterial and PhysicalSkyMaterial appearance
- Tweak colors to be less saturated and more balanced (in terms of hue).
  The cool blue sky is balanced by a warm brown ground,
  which makes reflections look closer to how they'd look like when using
  an HDRI panorama texture.
- Make the ground color dark on both ProceduralSkyMaterial and
  PhysicalSkyMaterial to reduce indoor light leaking, especially
  when using GI.
- Tweak the PhysicalSkyMaterial colors to be as close as possible
  to ProceduralSkyMaterial (with the default sun orientation).
- Tweak editor environment defaults to be identical to the default
  ProceduralSkyMaterial colors. Previously, the default editor sky
  color was different from the colors of a newly created
  ProceduralSkyMaterial resource.

Both new skies were tested without GI, with SDFGI and with VoxelGI.
They were tuned to look best when using ACES tonemapping with a
whitepoint set to 6, but they still look good with other
tonemapping operators.

Don't allow translucent colors in built-in sky material properties
The colors' alpha channel is ignored, so there's no point in
exposing it in the editor.

A few extra renames for classes which were missed in last week's PRs.
