citra_qt/dumping: Add dumping dialog
This is the main dialog of video dumping. This dialog allows the user to set output format, output path, video/audio encoder and video/audio bitrate. When a format is selected, the list of video and audio encoders are updated. Only encoders of codecs that can be contained in the format is shown.
