Original change's description:
> bluetooth: FakeBluetoothChooser impl.
>
> Implements the interfaces that FakeBluetoothChooser overrides. The
> mojom::FakeBluetoothChooser overrides are implemented by running
> |event_handler_| with the appropriate arguments. The BluetoothChooser
> overrides do nothing at the moment, since the base class is only meant
> to update the chooser user interface.
>
> This change also begins to partially convert a Bluetooth chooser test to test
> the interface and deletes the temporary tests that were created to test this
> API.
>
> This change reverts commit 42624492cd5e80855f1dd3a5a8146b258def2c2a, which
> reverted the original change. The original change caused the
> new-scan-device-added.html test to fail because of a Mojo validation error
> resulting from not updating the
> third_party/.../external/wpt/resources/chromium/fake_bluetooth_chooser.mojom.js
> file needed by the test.
