mac: Allow BGRX1010102 with SCANOUT_CPU_READ_WRITE.

With crrev.com/c/889863 we aligned SCANOUT{_CPU_READ_WRITE,} formats.

This CL adds BGRX_1010102 to {_CPU_READ_WRITE,}.

Additionally, it adds RGBA_8888 and BGRX_8888 to GPU_READ_CPU_READ_WRITE
and GPU_READ_CPU_READ_WRITE_PERSISTENT, effectively aligning all the format
lists for each allowed usage.
