Expose jscruntime to be consumed via Prefab

Summary:
This is the last library that we should expose via Prefab.
Thanks to cipolleschi 's work here moving the file to `/ReactCommon/jsc` folder
we can easily expose it to be consumed by third parties.

Changelog:
[Internal] [Changed] - Expose `jscruntime` to be consumed via Prefab
