Deprecate not passing parameter type to bindParam() and bindValue()

Q	A
Type	deprecation

The default for the parameter type primarily exists to save keystrokes for end users and works because in most cases binding an integer as a sting is okay for the underlying database platform and/or driver. It is fine to have such defaults in the wrapper-level "shortcut" methods like executeQuery($sql, $params) but they shouldn't be spread across different APIs at multiple architecture levels.

The ability to omit parameter binding type at the driver level is a PDO legacy which is a user-facing API as such but is a driver in the context of the DBAL.

Similar to #5556, this should have a minimal impact on the ORM and immediate users of the DBAL.

Doesn't this also apply to the wrapper-level Statement::bind*() methods? Those are called from userland code and I'm afraid we would make those calls unnecessarily verbose.

I totally agree to remove the defaults from the driver API though.

I believe there's no good reason to require types at the wrapper level. I'll revert the changes in the wrapper.
