tst_qflags: compile with QT_TYPESAFE_FLAGS

Browse Source 
In constExpr(), where code incorrectly assumed conversions to int or
uint were implicit, make them explicit.

In classEnum(), don't test bitwise operators between QFlags and
int/uint when QT_TYPESAFE_FLAGS is in effect.

Pick-to: 6.3
Fixes: QTBUG-101294
