AudioUtils bug fix for media playback

[rapterjet2004]

• possible fix to recently closed Not able to execute audio messages with Talk Android 17.1.0 #3325

Guarantees, that regardless of Codec State, the process will end at 3 seconds, sharp. Returning an Empty float array if not finished. This should make it compatible with slower devices. Also guarantees that the MediaExtractor is not null before queuing a new input buffer, which might stop some bugs that prevent the MediaCodec.BUFFER_FLAG_END_OF_STREAM flag from being set.
