… on to-many-collections

This fixes that using a `Criteria` with an `IN` or `NIN` expression on a to-many collection currently leads to an SQL error (doctrine#6173). The `ManyToMany` persister needs to know about the slightly different SQL syntax for `[NOT] IN ()`.

In the case of `[NOT] IN` expressions, the value will be an array, which also required me to change (I guess "fix") the parameter type handling. I have pulled the necessary code from the `BasicEntityPersister` and placed it as static helper methods in `PersisterHelper`.

This is somewhat inspired by doctrine#11516, which aims at fixing doctrine#11481: By re-using the parameter type handling code, it also fixes using backed enums in `EQ`, `IN` and `NIN` expressions within `Criteria` when `matching()` on one-to-many and many-to-many collections.
