  Clear11 Shader Optimizations and Shader Management Rework
  
  - ClearShader made into a class that manages all required shaders and input layouts for clears
  - ClearShader reuses VS for all clear types. This reduces shader compilation time and memory usage
  significantly
  - Use constantBuffer for color/z values instead of VB to decouple VB & VS from clearType and
  allowing for the same VS to be used for multiple clear types
  - FL10+ Devices: Generate positions using SV_VertexID in VS to avoid having to bind VB.
  - FL93 Devices: Use an immutable VB containing only position data (SV_VertexID not supported)
  - Implement CB cache. Incoming color/Z values checked against cache and CB/cache only updated if
  there is a mismatch. Significantly reduces the frequency of expensive CB map/rename operations
  especially in common scenarios where most/all clears use the same color/z values
