Update audio/musescore to latest upstream release, 3.5
- There's no minor (3.5.0) so fiddle a bit with the PLIST substitution
- Adds dependencies for Qt graphicaleffects
- Since musescore is not Qt 5.15 compatible (the palettes are broken, see https://musescore.org/en/node/307238) but usable-ish, I'm still committing this since it's no worse than the previous version w/ Qt 5.15, and users with an older Qt can build against that.
