osx: Fixed stage resize policy

Added initialization of minimum window size property on Cocoa
side. This property works when user change window size by mouse
dragging. But when size is changed by clutter_actor_set_size this
property will not help and was added another check in
clutter_stage_osx_resize. Also osx_get_geometry was refactoried
because it returns incorrect values in many cases but now size is
saved in [Window reshape] in requisition_width/height and this value
will be returned in any case to frontend.
