[ChangeLog][QTestLib] Add QTRY_COMPARE_{EQ,NE,LT,LE,GT,GE}_WITH_TIMEOUT
macros that repeatedly execute QCOMPARE_{EQ,NE,LT,LE,GT,GE} until either
the comparison returns true or the timeout expires. Also add
QTRY_COMPARE_{EQ,NE,LT,LE,GT,GE} macros that simply invoke the
*_WITH_TIMEOUT versions with the usual timeout of five seconds.
