Use new AT-SPI device API for keyboard monitoring when available
This is needed because gtk 4 no longer sends key notifications that atk-bridge can hook into, and, more generally, it removes the need to rely on the toolkit to forward key events. We now need to proactively notify AT-SPI when we want to grab a key. Unfortunately, X11 key grabs generate some events as a side-effect, so try to ignore these.
