PR: Promote unscoped enums in many other modules for PyQt6 compatibility

• Also add tests to check these additions work as expected.
• This is necessary to solve AttributeError when printing files with PyQt6 spyder#25332 and similar bugs in the future.

@dalthviz, this is ready for review. I promoted enums for modules with attributes listed in the enums.txt file available in qutebrowser/qutebrowser#5904 (comment).

I think it's important to promote enums wherever they are available since we're already supporting them but only for a few modules (like QtGui and QtWidgets).

Thanks @ccordoba12 ! I haven't checked the PR in detail but could it make sense to merge first #523 to check no test fails with Qt 6.8 bindings here?

[ccordoba12]

Sure, no problem.

Thanks @ccordoba12 !
