introduce generalized decorator to prevent invalid method calls
This introduces the ``_exclusive_against()`` utility decorator
that can be used to prevent repeated invocations of methods that
typically should only be called once.
An informative error message is now raised for a selected set of DML
methods (currently all part of :class:`_dml.Insert` constructs) if they are
called a second time, which would implicitly cancel out the previous
setting. The methods altered include:
:class:`_sqlite.Insert.on_conflict_do_update`,
:class:`_sqlite.Insert.on_conflict_do_nothing` (SQLite),
:class:`_postgresql.Insert.on_conflict_do_update`,
:class:`_postgresql.Insert.on_conflict_do_nothing` (PostgreSQL),
:class:`_mysql.Insert.on_duplicate_key_update` (MySQL)
Fixes: #5169
