fix #38371: element (sub)type shown untranslated

in select dialog.
Subtypes Notehead and Tremolo were translated already, this adds
translations for subtypes Accidental, Articulation, Fingering, Slur/Tie
and Staff/System text as well as for element type itself.
add bar line subtypes to the selection dialog
add text subtypes to the selection dialog

so far just those valid in frames.
Also simplify text::accessibeInfo(), to take existing translatations
rather than duplicate the (translation) effort.
Merge pull request #1438 from Jojo-Schmitz/translate_selection-dialog
