Summary:
The React-jsi Pod was serving two purposes: building JSI, and configuring JavaScriptCore as the JS engine.

By splitting the React-jsi Pod into React-jsi and React-jsi, we can start working towards de-coupling the JSI dependency from any particular JS engine.

Pods that depended on React-jsi, now depend on React-jsi and React-jsc.
One exception to this is React-hermes, which is only installed when Hermes is enabled, and thus does not require JavaScriptCore.
Upcoming commits should take care of removing the React-jsc dependency when Hermes is enabled, but it is out of scope for this commit.

Changelog:
[iOS][Changed] - The JSC Runtime is now provided by the React-jsc Pod instead of React-jsi. Libraries that declared a dependency on React-jsi in order to specifically create a JSC runtime (makeJSCRuntime()) will need to add React-jsc to their dependencies.
