Give UI nodes with Display::None an empty clipping rect (#10942)

Browse Source 
# Objective
Outlines are drawn for UI nodes with `Display::None` set and their
descendants. They should not be visible.

## Solution

Make all Nodes with `Display::None` inherit an empty clipping rect,
ensuring that the outlines are not visible.

Fixes #10940

---

## Changelog
* In `update_clipping_system` if a node has `Display::None` set, clip
the entire node and all its descendants by replacing the inherited clip
with a default rect (which is empty)
