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 a comment at the top of generated shaders This comment is useful to determine the origin of ShaderMaterials converted from built-in material types (such as CanvasItemMaterial or StandardMaterial3D). The Godot version is also included in case the shader needs to be regenerated with a newer engine version.

Style: Enforce separation line between function definitions I couldn't find a tool that enforces it, so I went the manual route: ``` find -name "thirdparty" -prune \ -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \ -o -name "*.glsl" > files perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files) misc/scripts/fix_style.sh -c ``` This adds a newline after all `}` on the first column, unless they are followed by `#` (typically `#endif`). This leads to having lots of places with two lines between function/class definitions, but clang-format then fixes it as we enforce max one line of separation. This doesn't fix potential occurrences of function definitions which are indented (e.g. for a helper class defined in a .cpp), but it's better than nothing. Also can't be made to run easily on CI/hooks so we'll have to be careful with new code. Part of #33027.

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.

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.

Style: Enforce separation line between function definitions I couldn't find a tool that enforces it, so I went the manual route: ``` find -name "thirdparty" -prune \ -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \ -o -name "*.glsl" > files perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files) misc/scripts/fix_style.sh -c ``` This adds a newline after all `}` on the first column, unless they are followed by `#` (typically `#endif`). This leads to having lots of places with two lines between function/class definitions, but clang-format then fixes it as we enforce max one line of separation. This doesn't fix potential occurrences of function definitions which are indented (e.g. for a helper class defined in a .cpp), but it's better than nothing. Also can't be made to run easily on CI/hooks so we'll have to be careful with new code. Part of #33027.

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.

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.
