drm/amd/display: Refactor dc_state interface

[WHY?]
Part of the dc_state interface that deals with adding streams and planes should
remain public, while others that deal with internal status' and subvp should be
private to DC.

[HOW?]
Move and rename the public functions to dc_state.h and private functions to
dc_state_priv.h. Also add some additional functions for extracting subvp meta
data from the state.
