Floss: Refactor hfp phone state function

1. Move as many duplicated code (such as phone_state_change
/ start_sco_call_impl / simple_at_response) into the
xxxx_impl functions.

2. Early return if not in MPS mode, we have not yet support
those function in production.

3. Seperate uhid_send_input_report into
uhid_send_hook_switch_input_report and
uhid_send_phone_mute_input_report to make it more
clear on the propose when using it.

4. streamline usage of phone_ops_enabled and mps_qualification_enabled
  * HfpCallbacks -> Only allowed in telephony or mps mode
  * DBus command -> Only allowed in mps mode
  * UHID output -> -> Only allowed in telephony mode
