kicad: update to 6.0.0

XXXTNN package phase is broken on macOS due to app bundling changes.
Extensive CMake surgery required. Will fix this in a follow-up commit.

New in 6.0:

- Modern, consistent look and feel
  KiCad 6.0 features a refreshed user interface designed to reduce the
  barriers of entry for new users
- Upgraded schematic editing
  KiCad's schematic editor has received its biggest overhaul ever for
  version 6.0
- Improved PCB design experience
  KiCad's PCB editor has had a complete look and feel upgrade

The following features are deprecated as of version 6.0:

  XSLT BOM generation scripts
  The SWIG Python API
