We rely on using `filter` is null or not to determine which type of
Bluetooth scanning method is going to be used (Classic of LE). Add a
variable to clearly indicate current scan type for better readibility.

Test: make RunSettingsRoboTests ROBOTEST_FILTER=DeviceListPreferenceFragmentTest

We only show connected hearing devices in the hearing devices page now.
When user pairing a device from pairing page and back to the hearing
devices page after the device is bonded, it's confusing no device shown
in the list because the device is still connecting to profiles. We
should show the connecting device to avoid confusion.

In Change Ia9750adb6b4c1424d084381e9d7c2ca8e7912391, addCachedDevices()
becomes async, but the filter is set outside of addCachedDevices(),
which makes the filter not apply to addCachedDevices().
Direct pass the filter to addCachedDevices() to fix this issue.
Also migrate the test to Kotlin so we can test coroutine.

There is heavy work to do when add device to list in the
DeviceListPreferenceFragment, off load these work from main thread
to solve the issue.
Make devicePreferenceMap a ConcurrentHashMap to avoid potential race
condition.
Also no longer use getCachedPreference(key) since we not put anything
into the cache, the fallback flow is always used.
Also in BluetoothDevicePreference.onPreferenceAttributesChanged(), move
more heavy work to background thread.
Using System.currentTimeMillis() to sort devices could cause flaky
because System.currentTimeMillis() could be same for different device,
use AtomicInteger instead.
