Add QEXPECT_FAIL to tst_QApplication::sendEventsOnProcessEvents

Test sendEventsOnProcessEvents has been noticed to fail when
qgtk3 (Glib) is loaded - Should be fixed in QTBUG-87137

Moving test from blacklist to use QEXPECT_FAIL as it's more
recommended until test is fixed in the relevant configurations.

QEXPECT_FAIL is selected to use as original investigator
reported also some cases when glib is working. Therefore
this approach is giving us more insight for further
investigation is it always failing with glib or not.

It was also reported linkage to zeroTimer test QTBUG-84291,
but not sure why removing that has affected to this one.

Update to QEXPECT_FAIL documentation to tell in first place
that XPASS is not only marking it as XPASS but also failing
the test. Same is mentioned in different location but it
needs more searching or testing how it works in real test.
