Reland "Fix dynamic buffer offset issues on D3D12 backend"
Cannot reproduce failure on GTX1060 and GTX2080Ti with latest driver. So disable
inherit test on compute shader and reland this patch
Original change's description:
> Fix dynamic buffer offset issues on D3D12 backend
>
> This patch fixes
> 1. Inherit dynamic buffer offsets : dawn chooses vulkan
> like inherit behaviour, so dynamic offsets need to be inherited.
> This patch adds inherit dynamic offsets between pipelines support and
> adds tests to cover it.
>
> 2. Dynamic offsets are skipped when groups have been set : in D3D12
> backend, when invoke SetBindGroup, dawn will check whether this group
> has already been set and skip updating root signature if the answer is
> yes. However, this behaviour will affect dynamic offsets update. With
> the latest patch, we always update dynamic offsets, even if they didn't
> change and adds tests to cover it.
>
> This patch also hit a dawn's issue about storage buffer validation in compute pass.
> Currently the validation is a workaround to avoid access conflicts but will impact
> using dynamic buffer offset in compute pipeline. Fix this issue is hard so disable
> related test for now and will enable it after the issue been fixed. File dawn bug
> 198 to track this
>
