fix #23846, at least partly

Seems not all of MuseScore accidentals have SMuFL counterparts.
Maybe twoor more glyphs need to get combined to form the missing ones?
fix comment

fix #23846, at least partly
use Stein-Zimmermann accidentals
Add rendering of capo chords, and capo setting.

For now, the capo position is a ChordName style setting. In the
future, it can be enhanced to allow capo position to be changed
within a score, using something like TempoMap or TimeSigMap.
If capo position is non-zero, the chord to be played with capo
applied is shown in brackets after the standard chord.

fix #23799: annotations deleted with chordrests

Segment annotations are currently deleted if the last chordrest in that
segment is deleted - either because you selected a region containing
this chordrest and hit Cut/Delete or because you lengthened a previous
chordrest to subsume this one.  But the 1.3, and expected, behavior is
that annotations remain even when chordrests are deleted.
uncomment measure tests
add tests

test new behavior - lengthening note and clearing selection preserve
chord symbols
