Major new things:

Minor new things:
* update from xcode CLT 12 to 12.4
This PR includes new stuff for creating the base box for parallels.
Still to do: using the new box type.
* update the vagrantfile stuff
* link the CI to the new version

* add vagrant plugins to installables
* Skip cppgraphqlgen ICE.
* [sdformat6] Remove unneeded include(FindBoost) which causes problems when the system cmake version doesn't match the one deployed by vcpkg.
