Subject: Forward extras from pre call external receivers to placeCall().

All extras that CallIntentBuilder handles will be stripped and read into the builder. Other entries will be send to telecom when the intent is build.

Renamed CallIntentBuilder.outGoingCallExtras for clarity.

Bug: 72877810
Test: Unit tests
PiperOrigin-RevId: 190301333
Change-Id: I9a8bf6664b270078d91dbfb3398f8990d243b9f8
