Description

Today when writing an event args to JS, one uses DispatchEvent; however this doesn't allow writing back JSI HostObjects, only allowing the simple types instead (int, string, bool, array, nested).
The idea would be to allow a WriteJSI api that allows modules/apps to pass JSI HostObjects into the JSValueWriter
