[Feature Request] Allow only displaying some specified callback function relationships in the callback graph

[CNFeffery]

In the current debug tools, the callback graph displays all callback function relationships by default (unless the callback functions are hidden based on 36c7171).

However, in many cases, the application functions that can be developed using Dash are becoming increasingly complex, making it difficult to identify effective information from the displayed callback relationship graph. Adding a new parameter to dash.Dash() to set all callback functions to be hidden by default, and adding a new parameter to callback() to allow the current callback function to be displayed in the callback graph, would facilitate callback debugging during the development of more complex applications.

Formally, it is similar to prevent_initial_callbacks in dash.Dash() and prevent_initial_call in callback().
