collectConflictsBetweenFieldsAndFragment function

void collectConflictsBetweenFieldsAndFragment(ValidationCtx context, List<Conflict> conflicts, Map<SelectionSetNode, FieldsAndFragmentNames> cachedFieldsAndFragmentNames, PairSet comparedFragmentPairs, bool areMutuallyExclusive, NodeAndDefCollection fieldMap, String fragmentName,)

Collect all conflicts found between a set of fields and a fragment reference including via spreading in any nested fragments.
