christopher waters 8d9fb8186f Initial work on SM6.6 support ...

- SM6.6 not enabled just yet.
- Adding our own defines of __SHADER_TARGET_MAJOR and __SHADER_TARGET_MINOR to mimic the DXC defines. Since we preprocess, we can't rely on DXC to define them for us.
- Adding support for 64bit atomic operations
- Changing part of Nanite PC atomic permutation selection to be based on DataDrivenPlatformInfo
- Fixing DXC shader debugging. The PDB section was still being stripped from the final DXIL.
