Don't use the `_before_type_cast` version of attributes in the form

We should never be ignoring valuable information that the types may need
to give us. The reason that it originally used `_before_type_cast` is
unclear, but appears to date back long enough that the reasons may not
be relevant today. There is only one test that asserts that it uses the
before type cast version, but it gives no context as to why and uses a
mock which does not simulate the real world.

Fixes #18523.
