Pass jsi::Runtime reference into CallInvoker::invoke* callbacks (#43375)

Summary: ## Changelog: [Internal] - As discussed with the team, it makes more sense to pass the reference to the correct `jsi::Runtime` object as an argument to the ` CallInvoker::invoke*` callbacks, that are provided by the user. There are various use cases when user would like to get a hold of the `jsi::Runtime` in the callback, and it makes sense, since it is guaranteed to run on the JS thread. So far people have been coming up with all kinds of workarounds for that, none of them safe enough. Reviewed By: rubennorte Differential Revision: D54643171
