Add shared bluetooth device functions by settings and systemui to settingslib.

These two functions are copied from `AvailableMediaBluetoothDeviceUpdater#isFilterMatched`, `ConnectedBluetoothDeviceUpdater#isFilterMatched`.

They check if a bluetooth device is a currently connected media device or currently connected other devices. They will be used both in settings (i.e., `AvailableMediaBluetoothDeviceUpdater#isFilterMatched`, `ConnectedBluetoothDeviceUpdater#isFilterMatched`) and systemui (i.e., the new bluetooth tile dialog).

Test: make RunSettingsLibRoboTests -j40
