tst_qsqlquery.cpp: Refactor runIntegralTypesMysqlTest()

Change 3370ab9119df09ca14f7d4641c555e60c1b3f478 introduced
warnings from MSVC:

tst_qsqlquery.cpp(4005): warning C4805: '==': unsafe mix of type 'const bool' and type 'int' in operation
tst_qsqlquery.cpp(4059): note: see reference to function template instantiation 'void runIntegralTypesMysqlTest<bool>(QSqlDatabase &,const QString &,const QString &,const bool,const T,const T)' being compiled
        with      [           T=bool       ]
tst_qsqlquery.cpp(4006): warning C4805: '==': unsafe mix of type 'const bool' and type 'int' in operation
tst_qsqlquery.cpp(4006): warning C4804: '/': unsafe use of type 'bool' in operation
tst_qsqlquery.cpp(4026): warning C4804: '+=': unsafe use of type 'bool' in operation

Extract an overload taking a QVector of values and use that for the
bool case instead of looping over min/max to generate a sequence of values
for bool.
