drm/amd/display: Extend inbox0 lock to run Replay/PSR
[Why] The inbox1 infrastructure is deprecated, so to support display power features requiring a DMUB interlock moving forward extend the inbox0 locking conditions to also include Replay or PSR. [How] Implemented a series of changes to improve HW lock handling: - Deprecated should_use_dmub_inbox1_lock() and guarded it with DCN401 flag. - Migrated lock checks into inbox0 helpers and added PSR/Replay enablement checks to ensure correct behavior. - Updated HWSS fast update path to acquire HW lock as needed using the new helpers.
