focusProxyAndInputMethods tests focus acquisition and inheritance with
a toplevel widget, acting as a focus proxy for a child.
X11 window managers are set to be bypassed, programmatic focus is set
with QApplicationPrivate::setActiveWindow().
The test is flaky on Linux/XCB, and therefore blacklisted on most
Linuxes.
This patch removes focusProxyAndInputMethods, considering that
- focus proxying is tested in tst_QWidget::focusProxy()
- window activation and focus inheritance are tested in
tst_QWindow::isActive()
Pick-to: 6.4 6.3 6.2 5.15
