Progressing towards https://gitlab.winehq.org/wine/wine/-/merge_requests/6569, and instead of dropping the old fields (https://gitlab.winehq.org/wine/wine/-/merge_requests/6731) now, which could be considered riskier.
- Avoid requesting unnecessary window config / state changes, - avoid triggering spurious window restore by updating _NET_WM_STATE on iconic windows, - simplify some code flow in preparation for delayed Win32 window state updates.

This was removed specifically to fix a KDE bug. Please see c5ec1585f6e5211a2b63e3435748210552250534 for details.

But requesting unnecessary changes triggers all sorts of race conditions, feedback loops and spurious window reconfiguration, making everything much more complicated.
We track the window manager changes, and if it sets the maximized state to a window on its own, we should then apply it to the Win32 state to make it consistent with X11 instead of trying to force the WM to do otherwise.

Fwiw I don't see the tests failing on KWin, either with or without this change. The only failure is at `win.c:10692`, which is the pre-existing focus race condition.

Okay, it probably doesn't matter anymore.
Tested this, and it seems fixes the issue with Office 2010+ in mutter (though didn't see this issue with kwin).
