feat(wm): add optional alt focus hack

This commit adds an optional focusing hack using simulated ALT key
presses to ensure that focus changes always succeed. As noted in the
documentation for LockSetForegroundWindow, the system automatically
enables calls to SetForegroundWindow if the user presses the ALT key.
