This implements the `fields` API in `_search` for runtime fields using doc values. Most of that implementation is stolen from the `docvalue_fields` fetch sub-phase, just moved into the same API that the `fields` API uses. At this point the `docvalue_fields` fetch phase looks like a special case of the `fields` API. While I was at it I moved the "which doc values sub-implementation should I use for fetching?" question from a bunch of `instanceof`s to a method on `LeafFieldData` so we can be much more flexible with what is returned and we're not forced to extend certain classes just to make the fetch phase happy.
