Use libyuv with downshift for 12/10 -> 8 bit when possible

When converting 12-bit/10-bit YUV images into 8-bit RGB, try to use
the following path first (before falling back to built-in conversion
using C code): 12/10-bit YUV -> 8-bit YUV (using libyuv) -> 8-bit
RGB (using libyuv).

This path is about ~40% faster than using the built-in conversion.
