a7127725ee Add simple functionality to wrap 1D dispatches into 2D or 3D as needed with minimal overhead, and add utility shader function to retrieve the linear index. 
- Makes the assumption (checked) that dimensions are at least 128 in both X and Y.

9fc8b1722d Refactored RDG ConvertToUntrackedX functionality into the RDG builder; renamed the operation to 'FinalizeAccess' for clarity, as the resource is considered finalized in the graph and will not transition to any other state. This operation now supports multiple resources, improving performance in cases where multiple resources are finalized back-to-back. Added validation to check that the user don't attempt to use it outside of its finalized state. Fixed up a few places where this assumption was being violated. Minor refactors in various places to use new API.

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.

076d131ceb Changed group dimension checks in ValidateGroupCount to ensures so that dispatches exceeding these limits hopefully don't take down the editor (but still prompt engineers that a technique is doing something bad and needs to be broken up into batches).
