wayland: implement new_constraint, remove_constraint and cursor_position_hint for PointerConstraintsHandler

Browse source 
new_constraint: check if the surface has pointer focus, keyboard focus, and if the pointer is within toplevel geometry or constraint region. If these conditions are met, then enable the constraint.

remove_constraint: apply last cursor position hint that saved in seat.

cursor_position_hint: save the cursor position hints provided by the client to the seat.
