Replace XY-offset closures with aligned_on_parent where possible

Replace XY-offset closures with aligned_on_parent where possible

It doesn't make sense to specify placement using multiple added
callbacks or closures when we can use aligned_on_parent. What's
more, aligned_on_parent should expose more consistent interface
for the users - affected grobs should now behave similarly to
LyricTexts and DynamicTexts. For example, this

\relative c'' \context Voice {
  \compressFullBarRests
  \override MultiMeasureRestNumber.self-alignment-X = #RIGHT
  R1*100
}

will result in right edge of the MultiMeasureRestNumber being
aligned on the right edge of the MultiMeasureRest.

Affected grobs:
- AccidentalSuggestion
- ClefModifier
- DoublePercentRepeatCounter
- Fingering
- GridLine
- MultiMeasureRestNumber
- MultiMeasureRestText
- PercentRepeatCounter
- StemTremolo

Expected changes in output: none.
