Remove UIImplementationProvider class and refactor UIManagerModule

Summary:
@public
This diff deprecates and deletes the UIImplementationProvider class.

It is not required to create an UIImplementation provider anymore, from now on the UIImplementation is created inside the UIManagerModule.

If you are using the UIImplementationProvider to create a ReactInstanceManager
e.g.:

```
    ReactInstanceManager =
        getReactInstanceManagerBuilder()
            ...
            .setUIImplementationProvider(...)
            ...
            .build();
```

Then you should just remove that line:
```
    ReactInstanceManager =
        getReactInstanceManagerBuilder()
            .set.....
            .build();
```
