Fix typing of related manager methods

Looking at the [related manager documentation][0] it isn't very clear
that the `bulk` argument only applies to `RelatedManager` and the
`through_defaults` argument only applies to `ManyRelatedManager`.

Based on the [related descriptors source][1], the following changes have
been made in this commit:

- The `bulk` argument has been added to `.clear()` and `.aclear()` for
  `RelatedManager`
- The `bulk` argument has been removed from all methods of
  `ManyRelatedManager`
- Additional methods using `through_defaults` have been added to
  `ManyRelatedManager`.
