API review cleanups/changes.

- Change onCreateIncomingConnectionFailed/onCreateOutgoingConnectionFailed
to accept the connection mgr phone account as the first parameter.
- For the video APIs, pass the target SDK of the caller into along so
that the Telecom permission check can have fallback behavior for older API
versions.
- Add guidance for how UX should be shown in onShowIncomingCallUi API.
API guidance follows how the Dialer app shows its notification and full
screen UX.

Test: Manual, CTS.
