Move the LATC and ETC1 enum values to GrPixelConfig. I also tried to put in checks in a few places to make sure that we weren't using these pixel configurations in places that we shouldn't be.
LATC is a DXT-esque alpha compression format that goes by a few other names (RGTC, 3DC). It might be useful to investigate using it to compress the alpha masks that we get from software rasterization. This patch set adds enums for that and recognition whether or not the device can support it.
