Lit->Lumen
Added Lit->Lumen submenu with 4 view modes - Lumen Scene, Lumen Reflection View, Lumen Surface Cache and Overview:
* Lumen Scene - same as ShowFlags->VisualizeLumenScene. Visualizes Lumen scene representation in highest possible quality, with highest possible view distance
* Lumen Reflection View - Lumen Scene, but with current reflections settings. Basically represents how things look in the reflections
* Lumen Surface Cache - visualizes surface cache and marks with pink missing surface cache coverage
* Overview - 3 Lumen view mode tiles, overlaid on top of normal view
Show->Lumen
Added Show->Lumen submenu with 6 flags, which allow to disable specific trace types (screen space, detail, global, far field), disable secondary bounces (radiosity) and disable Screen Space Directional Occlusion.
Show->Visualize
Removed �Lumen Scene� (replaced by Lit->Lumen->Lumen Scene view mode) and �Lumen Global Illumination� (replaced by r.Lumen.Visualize.IndirectDiffuse) from
Advanced visualization modes are accessible through r.Lumen.Visualize.Mode, which overrides current Lit->Lumen-> settings.
Misc changes:
* Renamed VisualizeLumenScene* to LumenVisualize*
* Moved shared visualize parameters to LumenVisualize.h
* Lumen HWRT visualize now uses same ray footprint as SWRT visualize
* Replaced HALF_WORLD_MAX with Lumen::MaxTracingEndDistanceFromCamera and Lumen::MaxTraceDistance in preparation for the LWC WORLD_MAX changes

1) Allows motion blur to output half and/or quarter res based on what the following passes needs. This avoids adding downsampling passes after
2) Runs FFT bloom on async compute to overlap with all the histogram exposure and local pre exposure stuf
3) Fixes a bug where r.Bloom.HalfResolutionFFT resolution was also dependent r.PostProcessing.QuarterResolutionDownsample
Frosty configurations:
1) Configures to use simple 2x2 dowsampling in post processing to be able to use the fast motion blur code path
2) Configures histogram exposure and local exposure to quarter res.

1) Motionblur have tile classification to improve VGPR pressure on fast motion blur gathering tiles
2) Motionblur tile classification can lower the gathering resolution to half res with r.MotionBlur.HalfResGather=1 on part of the screen with large motion vectors to reduce VALU costs under large movements, but still can compose with full res scene color without round trip to main memory to avoid adding memory bandwidth costs
3) TSR output a half res scene color in Mip1 so motion blur can dynamically sample half res under largement movements with r.MotionBlur.HalfResInput=1 to save memory bandwidth in the motion blur convolution
4) Number of direction samples becomes dynamic (and clamped to exisiting motion blur quality) based on length of motion vector to saves VALU with slow pixel velocities
5) Motion blur automatically avoid sampling full res center if the blur kernel completly occlude its to completly stop fetching full res to save memory bandwidth cost under large motions
Drops motion blur costs from 753us to 339us of motion blur costs + 40us additional cost in TSR to output half res in sandbox under movements.
And saves an average 0.3ms in the entire chase gameplay sequence.

For each pixel it shows the worst case missing mip level in all of the virtual textures sampled at that pixel.
Useful to analyze where late virtual texture page streaming is happening.
