Florin Malita fa7e9a813e [skottie] Switch to RapidJSON
- pull latest RapidJSON under third_party/externals/rapidjson
  (note: and older RS version is already pulled as part of angle2,
  and it is also checked in G3)

- add a thin Json porting layer (SkottieJson) to isolate RS
  idiosyncrasies

- convert Skottie to use the new helpers

- parse the DOM in-place (based on local experiments this is the
  fastest method)

Ta-da: Skottie now parses JSON ~10x faster!
