[Feature Request]: Widget visibility toggle

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

Adding a toggle to nodes' properties to show/hide all widgets that get their values from external nodes through inputs, allowing to reduce visual clutter.

This could be handled on an individual node basis and additionally as a general setting to serve as a default mode.

When setting "Hide inactive widgets" to **True**, the result would look as follows:


### Proposed workflow

1. Right-click on node
2. Click on "Properties Panel"
3. Toggle a boolean variable named e.g. "Hide inactive widgets"
