Use latest JavaScriptCore from npm

Summary:
- Use `latest` jsc-android from npm (devDependency of react-native)
- Use clang instead of the deprecated gcc
- Use libc++ instead of the deprecated gnustl
- Updated gradle and android plugin version
- Fixed missing arch in local-cli template
- `clean` task should now always succeed
- `clean` task deletes build artifacts
- No need to specify buildToolsVersion. It's derived.
- Elvis operator for more readable code
