Recent PR removes the ability for other windows to use MuseScore commands
I've been working on the Piano Roll Editor and recently noticed that many of the buttons stopped working. I was able to trace the issue to this recent PR:
fix #101991 Ignore shortcuts in menus #5982
Essentially, the logic now says that only the main window can issue these commands. However, it would be useful for other widows to be able to issue commands too. It seems like a lot of extra work to rewrite the play, rewind, etc. commands for every new window that needs to use them. It also breaks how these buttons have worked in up until this PR.
