Move to public plugins location

Summary:
^

So far, we had the 'uidebugger' plugin as a meta-only plugin.

This change moves the plugin to OSS space as it will ultimately be its right place.

It will also make it easier to iterate on it.

The plugin itself is not ready for consumption but at no point we are documenting or integrating it with our samples.
