Some improvements to backend texture creation.

This initializes more formats correctly with solid colors and relies
less on GrPixelConfig.

It also includes the changes to get gray8 read pixels working
and almost everything to initialize GL_RGB8 textures with data. Minor
stuff to follow to get RGB8 fully working and update test expectations.
