feat: add settings option to always show advanced widgets on all nodes (#8244)

Solved issue:
Currently, the display status of advanced widgets can only be set
individually for each node, but users would like to have a global switch
to always display all advanced widgets.

I also adjusted some related code to solve the issue of code
duplication.
