st/xa: Use PIPE_FORMAT_R8_UNORM when available

XA has been using L8_UNORM for a8 and yuv component surfaces.
This commit instead makes XA prefer R8_UNORM since it's assumed to have a
higher availability.

Also neither of these formats are suitable as destination formats using
destination alpha blending, so reject those operations.
