Add AvdManagerRunner.ListDeviceProfilesAsync() for device profile enumeration

Add ListDeviceProfilesAsync() and ParseDeviceListOutput() to
AvdManagerRunner. Runs 'avdmanager list device' and parses the output
into AvdDeviceProfile records (Id, Name, Oem, Tag).

Includes AvdDeviceProfile record model, 6 unit tests, and PublicAPI
entries for both net10.0 and netstandard2.0.

Closes #321
