[dx12,vulkan] Add support for P010 texture format (#8086)

P010 is a 4:2:0 chroma subsampled planar format, similar to NV12. Each
component uses 16 bits of storage, of which only the high 10 bits are
used. On DX12 this maps to DXGI_FORMAT_P010, and on Vulkan this maps to
G10X6_B10X6R10X6_2PLANE_420_UNORM_3PACK16.

The existing "nv12" gpu test module has been renamed to
"planar_texture", and a new test P010_TEXTURE_CREATION_SAMPLING has
been added similar to the existing NV12_TEXTURE_CREATION_SAMPLING. The
remaining tests in this module have been converted to validation tests,
and now test both NV12 and P010 formats.
