gallium: Introduce a new format to disambiguate PIPE_FORMAT_R8G8B8A8_UNORM.

Browse source 
PIPE_FORMAT_R8G8B8A8_UNORM now means just

  R8 G8 B8 A8

PIPE_FORMAT_R8G8B8A8_UNORM_REV means

  A8 B8 G8 R8

And the thumb rule is vertex buffers refer to PIPE_FORMAT_R8G8B8A8_UNORM,
while textures refer to PIPE_FORMAT_R8G8B8A8_UNORM_REV.

PIPE_FORMAT_R8G8B8A8_UNORM_REV is just a temporary name.
