QSql.TableType is wrong enum type in PyQt6

[ekhumoro]

Hello Phil

Previously, it was possible to OR together the values of QSql.TableType, but it's no longer possible to do this in 
PyQt6, as it's wrongly defined as an opaque enum, thus causing a regression when porting from PyQt5. In the Qt source, 
TableType is declared as an ordinary unscoped int enum, but it's clear from the docs that its members are meant to be 
used as flags:

     https://doc.qt.io/qt-6/qsql.html#TableType-enum

Of course, it's possible to work around the issue like this:

     flags = QSql.TableType(QSql.TableType.Tables.value | QSql.TableType.Views.value))

but it would be much nicer if the enum worked as intended. Could it please be converted to an enum type that supports 
the appropriate binary operators?
