tools/vs_code/*: Reworked VS code module; adding new version
Changes:
- In a new workspace, VS code is now configured properly at first run through the axii-provided 'run_once' mechanism.
- No symlinks any more: config files are copied and can be changed by the user without altering the files in the axii directory.
- Prettier output of the config script.
- New VS code version (October update)
