Display Lyrics in every track

[Danielku15]

See #2439

It would be a nice extension to show the lyrics of the first track on all tracks. This feature should be activated via new option (stylesheet?).

Technical details:

• We need to look at the applied lyrics of the same bar in the first track.
• We then take the relative tick position of the respective beat.
• We render lyrics on the displayed bar aligning it with a logic similar to:
  • If we have a beat at the exact same tick, we align it there.
  • If we do not have a beat at the tick, we interpolate the relative position between the two beats surrounding the lyric chunk.
• In multi-track rendering only render the automatic lyrics once.
