IMS-VT: When TTY is ON, do not allow MO VT call
When TTY mode is ON, the user SHOULD NOT be allowed to make
a Mobile Originating (MO) VT call and an UI alert message will
be displayed explaining MO VT call cannot be initiated.

Propagate the call substate changed message to the UI

IMS-VT : Set the flag to start call with speaker on for incoming VT calls
- There seems to be a race condition between when InCallUI
  enters the video mode and sets the speaker phone on and
  when call state changes to active.
- As a result, the audio route gets reset to earpiece as we
  are not setting speaker phone on flag for the incoming
  case. This change fixes that issue.

IMS-VT: Set speaker phone to true only if bluetooth or headset is not connected

IMS-VT: Convert emergency video call to voice call.
Convert emergency video call to voice call.
