Several tests failed due to side effects of client side
decorations. We explicitly disable this when initializing
the test to make things go smoother.
In addition, the setToolTip() test tries to set the mouse
cursor position programmatically, which is not possible
on Wayland.
And finally, the qWaitForWindowActive() falls back to
qWaitForWindowExposed() on platforms where explicit window
activation is not supported. This fixes a few issues, but
in cases like focusProxy(), it means we aren't actually
waiting for the WindowActivation event. Instead of testing
for exposed twice on such platforms (Wayland), we replicate
the logic from qWaitForWindowActive() instead and rely on
automatic window activation. If it fails, we do a QSKIP, so
this shouldn't cause any flaky test failures at least.
