[quartz] find_toplevel_under_pointer should not return _gdk_root

Browse Source 
The macOS WM has no root window. We fake one with a 1x1 window at the
origin that has no associated NSWindow. If the pointer is not on a
realized GdkWindow the hierarchical search will place it in the root
window even if it's nowhere near it. That's not valid, but returning it
from find_toplevel_under_pointer prevents Gdk from discovering when the
pointer is really over a GdkWindow. Return NULL instead so that the window
discovery is re-performed.
