Seungha Yang a6a4267c7b wasapi2: Add device provider implementation
Similar to device provider implementation of wasapi plugin,
this implementation supports only static probing.
But we can implement runtime device add/remove/update
monitoring using DeviceWatcher interface later.

See https://docs.microsoft.com/en-us/uwp/api/windows.devices.enumeration.devicewatcher
