 SearchFilter to support JSONField and HStoreField (#7121)

* SearchFilter to support Custom query Transforms

Since Some fields support `__` as a custom Transform for query lookups we needed to update the m2m checking code to handle search_fields that contain __ that are not relationships.

* Update documentation on SearchFilter to include references to JSON and HStore Fields.
