drm/amd/display: Refactor phantom resource allocation
[WHY?]
Phantom streams and planes were previously not referenced explcitly on creation.
[HOW?]
To reduce memory management complexity, add an additional phantom streams and planes
reference into dc_state, and move mall_stream_config to stream_status inside
the state to make it safe to modify in shallow copies. Also consildates any logic
that is affected by this change to dc_state.
