DTX AMR HR: fix inhibition
* Unlike in AMR FR, in AMR HR incoming ONSET have to be treated
differently depending on whether we've recently sent SID UPDATE or
EMPTY frame. Split ST_SID_U FSM state into 2 states to accommodate for
that and make sure that additional states specific to AMR HR are not
used for AMR FR.
* Avoid sending E_VOICE and E_SID_U in corresponding states
as those do not initiate FSM state transitions anyway. This decrease
extra load from FSM signalling which otherwise would be triggered on
per-frame basis.
* Introduce separate signal for SID First P1 -> P2 transition to avoid
confusion with E_COMPL and E_SID_U initiated transitions from P1
state.
* Don't init DTX FSM for SDCCH channels.
