[Media TTT] Update the sender view controller and the command line helper to
handle the sender @SystemApi states.

Bug: 216318437
Test: media.taptotransfer tests (still ignored because they were failing
on some cuttlefish builds, but they do pass locally)
Test: all adb commands work as expected (e.g. `adb shell cmd statusbar
media-ttt-chip-sender MyTablet TransferToThisDeviceSucceeded` shows the
succeeded chip)
