Open strings in StringData.

Allows to mark strings as open (non-fretted).
Defaults to fretted, keeping backward-compatibility with existing scores.
Adds an attribute `open="1"` in score (and instruments.xml) string data (defaults to "0").

Benefits:
- allows future support (also in TAB's) for string instruments with non-fretted strings (mainly but, I think, not only the lute family)
- gives correct fretting for non-fretted strings
- instrument range can more easily and automatically linked to actual string tuning
- as this will be eventually needed for better TAB support, the score reading/writing will be already able to manage it.
Small cosmetic changes to mscoreTAB fonts
Added comments and spaces
fix #28401: transpose chords appropriately in parts
Clean-up of mscore font

- Glyphs present in both legacy Emmentaler and SMuFL encoding have been unified: the Emmentaler code point now contains a reference to the SMuFL code point
- Large parentheses (U+E094, U+E095) changed to use the same graphic style of other Emmentaler parentheses (metrics not changed)
- Intersecting path in 128th rest (U+E10D) corrected
- Wrong path direction in U+E180 corrected
- Intersecting path in "volumeswell" (U+E845) corrected (required to separate a few FU the two parts, metrics unchanged)
- "wigglesawtooth" and "wigglesawtoothwide" (U+EABB, U+EABC) centred in glyph width
- All recently added or modified glyphs now pass validation
