d3d12: Add BlockCount and TexelCount typed integers

- Add new typed integers TexelCount and BlockCount, along with strongly
  typed versions of TexelOrigin3D, TexelExtent3D, and TexelBlockInfo.
- Modify TextureCopySubresource, the return value from the
  TextureCopySplitter API, to use these new strong types.
- Update TextureCopySplitter implementation to convert input args to
  strong types and use them.
- Update CopySplitTests to use strong types.
- Update CopySplitTests to also tests the relaxed versions of
  TextureCopySplitter API (these were completely untested).
- Fixed a bug in
  Compute3DTextureCopySubresourceWithRelaxedRowPitchAndOffset when
  setting `copyInfo1->bufferSize`, which was found by using strong
  types.
- Fixed a bug in CopySplitTests BaseBufferSpecs which when computing
  bytesPerRow.
- Added SCOPED_TRACE to CopySplitTests so that test failures can
  actually be debugged, since each test actually performs multiple
  subtests.

A few things worth noting:
- TexelCount and BlockCount are uint64_t, not uint32_t, because as typed
  integers, they do not participate in type promotion to uint64_t, which
  was being relied on for computing buffer offsets and such.
- There are multiple type conversions between
  Origin3D/Extent3D/TexelBlockInfo and their strongly typed
  counterparts. Future CLs will remove many of these, and should
  eventually only occur in one place, probably post-validation.
