Adding interface to wrap surface interactions for LogBox

Summary:
This diff introduces a new interface named `SurfaceDelegate`. The interface abstracts the API for interacting with a surface, which is required for platforms other than mobile to implement how it wants to show and hide a surface. For existing Mobile use cases, the `LogBoxDialogSurfaceDelegate` is provided as a fallback solution so everything still works.

Changelog:
[Android][Added] - Add SurfaceDelegate abstraction to support interaction in multiple platforms and provide default implementation in LogBoxModule
