[Feature Request] Dev Tools Callback Graph - Allow hiding specific `DashDependency` objects

Related to the recent callback graph usability improvements, it would be extremely helpful to allow certain DashDependency objects to be completely excluded from the Dev Tools callback graph.

For example, being able to mark dependencies like the following as hidden:

Output("irrelevant_store", "data", hidden=True)

This would allow app authors to hide implementation details and internal wiring, keeping the callback graph focused on the dependencies that actually matter. For complex applications, this would significantly improve readability and reduce noise in the graph.
