V2 Node Search (+ hidden Node Library changes) (#8987)

## Summary

Redesigned node search with categories

## Changes

- **What**: Adds a v2 search component, leaving the existing
implementation untouched
- It also brings onboard the incomplete node library & preview changes,
disabled and behind a hidden setting
- **Breaking**: Changes the 'default' value of the node search setting
to v2, adding v1 (legacy) as an option
