Switch to using ViewManagerResolver for view managers

Summary:
Right now the FbReactInstanceDelegate provides a list of view managers to the instance during initialization, this means that we're basically eagerly loading all of the view manager classes.

In this change we use ViewManagerResolver instead.

Changelog:
[Android][Changed] - Move ViewManagerResolver into a seperate file
