[PATCH] D42895: [libclang] Add `CXSymbolRole role` to CXIdxEntityRefInfo

CXIdxEntityRefInfo contains the member `CXIdxEntityRefKind kind;` to
differentiate implicit and direct calls. However, there are more roles
defined in SymbolRole. Among them, `Read/Write` are probably the most
useful ones as they can be used to differentiate Read/Write occurrences
of a symbol for document highlight in a text document.

See `export namespace DocumentHighlightKind`
