fix #7282 - support additional root/bass styles

German, Italian, lower case minor
more flexible root handling

Allow "sym" declarations in chord description file to take string
values, support class="note" to differentiate "b" used as note name from
"b" used as flat (also "mi" for note name versus minor), allow lower
case letter on its own to imply minor if lowerCaseMinorChords is set by
using "=" as a special hidden abbreviation.
fix #11115: support solfeggio note names

Actual support was added in previous commits; this is really just
cleanup and renaming the option from "Italian" to "Solfeggio".
Gernan chords use As and Es, not Aes and Ees

Also add hooks for French spelling of Re

fix #21704: imported chords do not render

Recent changes to default style chordlist handling resulted in imported
scores never loading a chord list at all, causing them to render
incorrectly (no root or bass).  This is a proposed fix for that specific
issue that also addresses other potential problems in chordlist handling
(honoring the distinction between a truly empty chordlist and one that
merely contains no chord id's but does contain sym & token definitions).
