Fix check for is_maximized in x11 to require both horizontal and vertical

Browse Source 
Fixes #103522

Persistent window state doesn't work if your window is 'tiled' in X11
gnome

3.x checks for `horz && vert`
4396e98834/platform/x11/os_x11.cpp (L1708)

4.x also checked `horz && vert` until this change where it was switched
to `horz || vert`

The corrected logic is:
Check `horz && vert` for 'is_maximized'
Check `horz || vert` for 'can_maximize'
