PixelShaderGen: Don't emit bounding box shader code for old UIDs when disabled
...
If bounding box is enabled when a UID cache is created, then later disabled,
we shouldn't emit the bounding box portion of the shader.
Fixes pipeline creation errors on D3D12 backend for this case.

PixelShaderGen: Split bbox into seperate variables
...
The Metal shader compiler fails to compile the atomic instructions
when operating on individual components of a vector. Spltting it
into four variables shouldn't make any difference for other
platforms, as they are accessed independently.

VideoCommon: remove unnecessary floor()
...
floatindex is clamped to the range [0, 9]. For non-negative numbers
floor() is equivalent to trunc(). Truncation happens implicitly when
converting to uint, so the floor() is unnecessary.

PixelShaderGen: Ensure all components of ocol1 are initialized
...
This was causing a warning in the shader compiler, as the rgb components
were not initialized. Which shouldn't be an issue, as the rgb is not
used in the blend equation, only the alpha. However, the lack of
initialization causes crashes in Intel's D3D shader compiler, so we'll
play nice and initialize all the channels.

LightingShaderGen: Always calculate lighting for both color channels

Cel-damage uses the color from the lighting stage of the vertex pipeline
as texture coordinates, but sets numColorChans to zero.
We now calculate the colors in all cases, but override the color before
writing it from the vertex shader if numColorChans is set to a lower value.

VideoBackends: Clear uid bits that are unused for the current backend
...
Currently, this is only the logic op bit, but this will be extended to

VideoCommon pipelines, this state will be part of the pipeline UID
anyway, and we can mask it out in the backend by using a two-level map,
so the shaders/programs are shared.
