[Media TTT] Allow additional transitions from the SUCCEEDED/FAILED
states.

For the _SUCCEEDED or _FAILED states, those represent the end of a
transfer process. So, from those states, we should allow any state
that is the start of a new transfer process.

Bug: 221265848
Test: manual: verified that the new transitions are allowed when using
the adb commands
Test: atest MediaTttSenderCoordinatorTest
