[Media TTT] Add a chip view and controller for the receiving device.

Screenshot of chip is attached to the bug.

adb command to trigger receiver chip: `adb shell cmd statusbar
media-ttt-chip-add-receiver`. The command to trigger the sender chip is
now `adb shell cmd statusbar media-ttt-chip-add-sender Tablet
MoveCloserToTransfer`.

Fixes: 203800646
Test: manual
Test: MediaTttChipControllerReceiverTest
Change-Id: I32843a8b6f60b563bca192cbd2456a5d88a6ed24
