[WARP][DXC][D3D12] `QuadReadAcrossY.fp64.test` failure for WARP on x64 architecture

[kcloudy0717]

WaveOps/QuadReadAcrossY.fp64.test is failing on WARP-AMD for both dxc and clang. In both cases the behaviour is the same: it returns all zeros (appears to do nothing).

This is due to the following error, visible when run with -debug-layer -validation-layer specified:

gpu-exec: error: Failed to map result.

DXC log. Clang log.
