dri: add createImageWithModifiers2 interface
With the addition of createImageWithModifiers usage flags were
dropped, as it was believed at the time that modifers will be a
full replacement for the usage flags. This has turned out to be
untrue, as modifiers are not able to describe buffer placement.
Add a new version of the interface, that allows to specifiy
use flags in addition to the modifier.
