mesa/format_utils: Add a fast-path for RGBA to BGRA
This is similar to an existing fast-path, but this is for an array
source while the existing one is for an array destination.
Firefox can hit this case for WebGL when GL compositing is not used.
For a WebGL sample on the Panfrost driver, the frame-rate increased
from 19.4 fps to 20.6 fps, which is a 6% gain.
