VGM Codec: Improve time and fade behavior. Tweak minor misc.

Prevents cutoff of tracks, especially short ones:
* Extend looped tracks by fade length to fade at start of loop repeat.
* No fade occurs for non-repeating track only having an intro.
* Uses id3.tail_trim field to store fade duration.

Use libGME built-in elapsed time reporting instead of custom calculation:
* libGME already reports in milliseconds.
* Don't advance time counter when Repeat == One. It just runs the progress
  over the length limit.

Fix a comment about sample rate and set the reported bitrate to be
accurate for 44.1 kHz stereo.
