drm/xe/sysctrl: Add helper to query application status

Browse source

Add xe_sysctrl_check_app_status() to query the state of a System
Controller application using get_app_status_by_id mailbox command.

The helper maps xe_sysctrl_app_id values to firmware application
IDs and returns the reported application state. Add a convenience
wrapper to check diag firmware application readiness.
