feat(cli): install rawstor packages in core VM when requested by bootstrap

Reads the with_rawstor flag from spec.json (set by exordos CLI's
`bootstrap --with-rawstor --pool-agent-placement=core`) and installs
librawstor + python3.12-rawstor during first-boot bootstrap, alongside
the existing element installation steps.
