New project: crosvm (#10284)

crosvm fuzzing is currently running as part of ChromeOS infra, where the
project originated.

Crosvm has since become an independent project with separate
infrastructure and we would like to move fuzzing out of ChromeOS as
well.

Tested with `python3 infra/helper.py check_build crosvm`
