Fixes#73374
As of godot 4 On windows/osx the game window will be frozen and will not
be updated.
In the debugger loop it calls
OS::get_singleton()->process_and_drop_events();
which allows windows/osx to handle system events. If the window doesn't
handle these events then both systems will judge the window to be 'not
responding' (osx beachball cursor)
When the event processing code was migrated from OS to DisplayServer the
process_and_drop_events() logic was moved to DisplayServer, but the call
inside the remote debugger pause loop was not updated to call the
DisplayServer version, there are currently no implementations of
OS::process_and_drop_events() so i removed it and switched to the new
DisplayServer::force_process_and_drop_events() method.
