Carlos Garnacho 1e990ad823 core: Change meta_display_get_grab_op() to has_grab()
Make this public API check just return a boolean about whether
there is an existing grab, instead of exposing MetaGrabOp.

It is desirable to avoid exposing details like
META_GRAB_OP_WAYLAND_POPUP, so that MetaDisplay and wayland
grabs can port to ClutterGrab at their own pace, but also
this further information is unused.

This is likely to be temporary API anyways, after both
MetaDisplay and wayland grabs port to Clutter, it will be
possible to check the ClutterStage for all of them.
