Handle generic-midi bindings per session.

This allows to special-cases session-specific control-surface state.
e.g. midi-learn.

Only restore midi-learned, session-specific, bindings when loading a
session with generic-midi enabled.

Also dis/re-enable generic-midi resets midi-learned, but no other
session-independent settings.

This also handles the edge case:
 1) load global config, generic-midi = ON, w/ bindings.
    state is remembered as cpi->state
 2) load session-condig, generic-midi = OFF, cpi->state is retained
 3) user enables the surface, cpi->state from (1) is applied.
 -> invalid bindings applied -> fail
