laura hermanns 67217ad5ad [Shaders] Replace DXC rewriter with new SPIRV-Tools pass to pack "$Globals" cbuffer. ...

- Adds StructPackingPass to SPIRV-Tools which re-assigns all struct member offsets of the global cbuffer ("type.$Globals" when translated in DXC/SPIR-V) according to the std140 memory layout rules.
- Remove DXC rewriter from shader backends as the shader minifier can already handle the majority of dead code removal.
- Rebuilt DXC for Win64, Mac, Linux.
