This patch adds the support of BC5 formats on D3D12 backend. On D3D12,
the "rowPitch" refers to the number of bytes in a row of blocks (which
covers up to 4 scanlines at once) for the textures in BC formats.
This patch also adds the related end2end tests for four typical cases of
B2T and T2B copies on D3D12:
(1) copyBytesPerRowPitch + byteOffsetPerRowPitch <= rowPitch and
texelOffset.y == 0
(2) copyBytesPerRowPitch + byteOffsetPerRowPitch <= rowPitch and
texelOffset.y > 0
(3) copyBytesPerRowPitch + byteOffsetPerRowPitch > rowPitch
(4) texelOffset.z > 0

This includes a bunch of fixes for clang warnings in Windows specific
code that was only compiled by MSVC previously. This also tidies up some
BUILD.gn issues on Windows.
