gallium/u_transfer_helper: Add support for separate Z24/S8 as well.
u_transfer_helper already had code to handle treating packed Z32_S8 as separate Z32_FLOAT and S8_UINT resources, since some drivers can't handle that interleaved format natively. Other hardware needs depth and stencil as separate resources for all formats. For example, V3D3 needs this for 24-bit depth as well. This patch adds a new flag to lower all depth/stencils formats, and implements support for Z24_UNORM_S8_UINT. (S8_UINT_Z24_UNORM is left as an exercise to the reader, preferably someone who has access to a machine that uses that format.) Reviewed-by: Eric Anholt <eric@anholt.net>
