Depth/stencil copies of partial subresources is disallowed in
WebGPU because this is a D3D12 restriction. This restriction
need also to be enforced on B2T, T2B and WriteTexture.
This CL also fixes the subresource whole size calucation to use
the mip level. Previously, the 0th level size was always used.
This CL updates the validation to be correct and adds tests.
The DepthStencilCopy tests are factored into smaller helpers to
reduce code duplication.

In the test DepthStencilCopyTests/FromStencilAspect we are writing into
gl_FragDepth but we disable the depth writing when creating the render
pipeline, which causes Intel Mesa driver hangs when the test is running
on it. In this patch we try to add workaround to this issue by enabling
the depth writing.
