Dillon Varone c24bb00cc6 drm/amd/display: Refactor DC update checks

[WHY&HOW]
DC currently has fragmented definitions of update types.  This changes
consolidates them into a single interface, and adds expanded
functionality to accommodate all use cases.
- adds `dc_check_update_state_and_surfaces_for_stream` to determine
  update type including state, surface, and stream changes.
- adds missing surface/stream update checks to
  `dc_check_update_surfaces_for_stream`
- adds new update type `UPDATE_TYPE_ADDR_ONLY` to accomodate flows where
further distinction from `UPDATE_TYPE_FAST` was needed
- removes caller reliance on `enable_legacy_fast_update` to determine
  which commit function to use, instead embedding it in the update type
