gowin: Add constraints on primitive placement.
Added support for the INS_LOC instruction in the constraints file (.CST), which is used to specify object placement. Expanded treatment of IO_LOC/IO_PORT constraints, which now can be applied to both ports and IO buffers. Port constraints have priority. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>
