Revert "i965: Create ARGB2101010 DRI configs"

Exposing 10-bit color configs confuses too many applications that try to
use the chooser to pick an 8 bit config.  The chooser consider an fbconfig
with more bits a better match and will thus give a 10 bit config when an
application asks for a config with GLX_RED_SIZE 1 or 8.

One key example is glxinfo, which does this, and then doesn't specify that
it needs a config where GLX_DRAWABLE_TYPE has the GLX_WINDOW_BIT set.
This way it ends up with a 10 bit config that it can't use to create a
GLX window and fails to log extensions.

This reverts commit f354bcc1770e9df88db51eba5a4543a09ca6d128.
