Summary: Now the event delive pipeline supports `JSI::Value`-based payload. Instead of passing `folly::dynamic`, now we are passing `std::function<jsi::Value(jsi::Runtime &runtime)>` as factory that can build a `JSI::Value` with given `jsi::Runtime` and any captured data. The old (now legacy) way of calling `EventEmitter::dispatchEvent(..., const folly::dynamic &payload, ...)` is also supported.
