Add ResolvableSource interface for potentially opening entries directly based on some URI via a share intent

Implemented as an intermediate step in the existing Global Search share intent workflow.
If any source manages to resolve the URI (e.g., a URL, a slug, etc.), the resolved SManga entry
is directly opened. If nothing gets resolved, continue to a Global Search.
