[PowerDisplay] Rescan monitors on display wake (#47876)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request

1. Subscribes to GUID_CONSOLE_DISPLAY_STATE so PowerDisplay rescans
monitors when the console display wakes from sleep — previously, woken
monitors stayed unrecognized until the user manually re-triggered
discovery.
2. Locks the PowerDisplay UI immediately on wake to block stale
interactions before the rescan completes.
