Subject: [PATCH] tst_QMetaEnum: add round-trip testing to valueToKeys()

... adding a bit of test coverage of keysToValue().

This is not intended as a reproducer for QTBUG-118240, because that
is concerned with inputs valueToKeys() cannot produce.

Task-number: QTBUG-118240
Pick-to: 6.6 6.5 6.2 5.15
Change-Id: I5d772be4231717cdbb5d033b1f11ae31e4c57c0b
