Allow for customization of notation elements "stacking order" in parts

Your idea

Bring back stacking order for text styles and notation markings in parts

Problem to be solved

One of the notation conventions in the gig I'm doing encourages measuring numbers in the center of each bar. However, using MuseScore makes this quite difficult. Even if I use the offset tool for every single element in only the parts, I then have to adjust the auto-place in each part, which becomes very laborious with my time constraints.

A stacking order would allow me to keep measuring numbers at the time no matter what, notwithstanding autoplace or anything like that.

I've attached an example of what I would like MuseScore to optimize:

Prior art

They solve it by simply making it an option to put measure numbers at the very center at the bottom edge of the instrument stave

The issue names parts, text styles, notation markings, measure numbers, autoplace, and the offset tool, but no files, tests, or entry points. Start by locating the parts layout and autoplace implementation, then determine how stacking order should interact with those controls. Done means users can customize stacking order for notation elements in parts without manually adjusting each element.
