andrew lauritzen 9b0a6fab9d Remove complete shadow maps and replace with direct VSM sampling ...

- Move VSM parameters into a single uniform buffer; required for base pass rendering.
  - SRVs are initialized to dummy data until they are computed during the frame and subsequently updated before any VSM sampling.
  - Make names and usage more consistent with other UB bindings in mesh passes
- Direct injection of VSM into translucent volume and fog
- Support VSM sampling in forward lighting shaders
  - Enabled and bound currently for translucent forward and single pass water meshes
- Support VSM sampling in sky atmosphere and cloud rendering
  - NOTE: Sky atmosphere LUT pass currently executes before BasePass and ShadowDepths so it will not sample proper data and throw a warning. Moving passes around to address this will come in a future commit.
