sanitizers: Use the ZeroInitWorkgroupMemory transform
...
Zero the workgroup memory for all backends.
We can probably disable this for the backends that support workgroup zeroing, but that's an optimization we can perform later.

writer/hlsl: Implement atomics

Workgroup atomics are far more conventional, but very little code can be shared between these two code paths.
