glamor: Eliminate GLAMOR_USE_SCREEN and GLAMOR_USE_PICTURE_SCREEN

Remove these defines as we start to remove support for non-standard
glamor layering as used by the intel driver.

v2: Rebase on the blockhandler change and the Xephyr init failure
    change (by anholt), fix stray NO_DRI3 addition to xwayland.
