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.
