Add QCOMPARE_{EQ,NE,LT,LE,GT,GE}()

[ChangeLog][QTestLib] Add QCOMPARE_{EQ,NE,LT,LE,GT,GE}()
macros. These new macros behave similarly to QVERIFY(a op b),
where 'op' is ==, !=, <, <=, >, >= respectively, but print
a formatted error message with argument values in case of failure.
The formatting is done lazily, which means that the strings will
be generated only when the comparison fails.

Also add a new test for tst_selftest and generate expected output
for it.

Fixes: QTBUG-98873
Task-number: QTBUG-98874
