fix #23785: chord symbol text style changes

Changes to chord symbol text style were not taking effect until reload.
This change forces a render() call on all chord symbols if the text
style changes.
remove hard coded style name
Add to MScore font a repeat dot glyph separate from augmentation dot.

SMuFL distinguishes between the augmentation dot and the repeat dot (used in repeat bar lines).

This patch:
- adds the MScore font a separate glyph for repeat dot. The glyph is encoded in the same code point used by SMuFL and is currently a simple reference to the augmentation dot.
- changes the BarLine class draw code to use this glyph instead of the augmentation dot.
fix #23783: chord symbol text style properties

Adds support for X, Y, horizontal alignment, and vertical alignment.
Improves compatibility for 1.3 scores, which relies on text style Y to
set chord height, also allows for chord symbols centered over notes (see
#10355).
fix #23782: suppress Harmony Properties dialog

Remove default keyboard shortcut, only display in context menu if "-e"
option used
