Move "movex-react/movex-local" into it's own library

[GabrielCTroia]

What?

At the moment the libs/movex-react contains the movex-local code, but this can be it's own separate library. Probably called something like movex-local-master or even 'movex-react-local-master'.

Why?

To reduce the movex-react library file size!

Open to discuss

Although one issue might arise once we support more frameworks, as then we need to add a movex-[framework]-local-master for each one! I think this deserves more thinking!
