This adds a new experimental r.TSR.History.HighFrequencyOnly.
This remove r.TSR.Translucency.SeparateTemporalAccumulation because translucency is otherwise too ghosty anyway, avoiding an increase of shader permutation.

Adds 20us to TSR's DilateVelocity, but eliminate MotionBlur's velocity flatten that is 120us on console.

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.
