* Port `ujust set-kargs-hardening` and `remove-kargs-hardening` to Python. * Better formatting and user input checking for `set-kargs-hardening`. * `ujust set-kargs-hardening` now *removes* optional kernel arguments in the classes not selected by the user (e.g. `nosmt=force` is removed if already present if the user selects "no" for its prompt). * Centralize the list of kernel arguments: the default kargs are now only in `/usr/lib/bootc/kargs.d`, everything else (including the audit script) reads from there. This should make modifying the list of kargs less error-prone as we don't have to ensure the lists stay in sync. * Sort kargs lexicographically in `kargs.d`. * Make Nvidia kargs ujust scripts Nvidia-only.

This centralizes the list of Nvidia-specific kargs as well, so the list is only present in `/usr/lib/bootc/kargs.d` and both the scripts read the list from there.
This allows kargs to be set non-interactively from other Python code.
