I did some experimentation and C++20's `using enum` feature solves this problem perfectly. We continue to maintain the same user experience without requiring an extra `EnumName::` at all use sites...

Rebased because this touches `IpAddress.cpp` which was recently modified and tested. No changes made.

@vittorioromeo Could you weigh in on how, if at all, SFML ought to make use of scoped enumerations?

Fixed conflicts with `master`

Rebased and reformatted because of #2159

Does the team have any more thoughts on this?

Rebased on master and removed some old changes to Audio code left over from an older incarnation of this branch.

Monthly rebase just for the sake of it. Nothing changed.

Rebased to catch up with `master`. No changes required.

I haven't seen these deprecation warnings in a while. I think this got fixed in c824d3d57a5ef905a4453c9c2fde892c2aa8737b.
