dri: Add config attributes for color channel shift
The existing mask attributes can only support up to 32 bpp. Introduce
per-channel SHIFT attributes that indicate how many bits, from lsb towards
msb, the bit field is offset. A shift of -1 will indicate that there is no
bit field set for the channel.
As old loaders will still be looking for masks, we set the masks to 0 for
any formats wider than 32 bpp.
