clayjohn 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 a shadow opacity property to Light3D
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.

clayjohn 0c65ed38a6 Treat specular less than 0.02 as occlusion
This is a very common hack used in almost all PBR renderers to allow removing specular contribution in dielectric materials

Make Decal's `modulate` property affect emission color as well
This can be used to recolor special effects such as fake area fog
without having to create separate textures for each color.

- Improve the Decal class documentation.

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.

Use less blur for distant directional shadow splits
This makes the transition between shadow splits less noticeable,
specially when the expensive Blend Splits property is disabled.

jfons e69d762dd0 Add color pass flags to Forward Clustered renderer
This commit removes a lot of enum values related to the color render pass in favor of a new flag-bases approach. This means instead of hard-coding all the possible option combinations into enums, we can write our logic by checking a bit-mask.

The changes in rendering_device_vulkan.cpp add support for unused attachments. That means RenderingDeviceVulkan::framebuffer_create() can take null RIDs in the attachments vector, which will result in VK_ATTACHMENT_UNUSED entries in the render pass.

This is used in this same PR to establish fixed locations for the color pass attachments (only color and separate specular so far, but TAA will add motion vectors as well). This way the attachment locations in the shader can stay the same regardless of which attachments are actually used.

Right now all the combinations of flags are generated, but we will need to add a way to limit the amount of combinations in the future.

clang-format: Disable alignment of operands, too unreliable
Sets `AlignOperands` to `DontAlign`.

`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.

jfons c46d1ea2b2 Fix shadow disabling settings
Fixes the SHADOW_CASTING_SETTING_OFF setting in
GeometryInstance3D and the "shadows_disabled" render

JFonS c571e4a7f4 Implement distance fade and transparency
The built-in ALPHA in spatial shaders comes pre-set with a per-instance
transparency value. Multiply by it if you want to keep it.

The transparency value of any given GeometryInstance3D is affected by:
   - Its new "transparency" property.
   - Its own visiblity range when the new "visibility_range_fade_mode"
     property is set to "Self".
   - Its parent visibility range when the parent's fade mode is
     set to "Dependencies".

The "Self" mode will fade-out the instance when reaching the visibility
range limits, while the "Dependencies" mode will fade-in its
dependencies.

Per-instance transparency is only implemented in the forward clustered
renderer, support for mobile should be added in the future.
