avdevice: add info about media types(s) to AVDeviceInfo

An avdevice, regardless of whether its category says its an audio or video device, may provide access to devices providing different media types, or even single devices providing multiple media types. Also, some devices may provide no media types. dshow is an example encompassing all of these cases. Users should be provided with this information, so AVDeviceInfo is extended to provide it.
