SourceResolver is separated from MFPlayerSession to handle the work of resolving a media source
asynchronously. You call SourceResolver::load to request resolving a media source asynchronously,
and it will emit mediaSourceReady() when resolving is done. You can call SourceResolver::cancel to
stop the previous load operation if there is any.
