Pull createNewScreen entry point into dri_util.c.

This pulls the top level createNewScreen entry point out of the drivers
and rewrites __driUtilCreateNewScreen in dri_util.c to be the new entry point.

The change moves more logic into the common/ layer and changes the
createNewScreen entry point to only be defined in one place.
