tvix/store/fuse: Consider switching to cloud-hypervisor/fuse-backend-rs for FUSE

There's couple advantages of this crate over fuser:

It has an async interface (though it still requires a sync implementation)
It is compatible with virtiofs which means it can be used with microvms

The latter is the more interesting part to me, since you could boot a NixOS VM with the Tvix Store set up without having to deal with setting up FUSE in the guest initrd

Working on this in cl/9341

The CL moving it over landed 🎉, and virtiofs is also WIP. This can be closed.
