misc: make MSRV workspace-wide for cloud-hypervisor dependencies

Moves the MSRV requirement to the workspace and expands it to all
cloud-hypervisor dependencies and dev-dependencies.
This improves discoverability for new contributors working on crates
other than the cloud-hypervisor itself and creates consistency regarding
the MSRV of cloud-hypervisor dependencies.
Functionally, this doesn't change anything for dependencies of the
cloud-hypervisor crate as the MSRV requirement is already enforced by CI
when building the cloud-hypervisor with the MSRV versioned compiler.
