sandbox-bindmount: persist mount information

Browse Source 
Without this, if the shim dies, we will not have a reliable way to
identify what mounts should be cleaned up if `containerd-shim-kata-v2
cleanup` is called for the sandbox.

Before this, if you `ctr run` with a sandbox bindmount defined and SIGKILL the
containerd-shim-kata-v2, you'll notice the sandbox bindmount left on
host.

With this change, the shim is able to get the sandbox bindmount
information from disk and do the appropriate cleanup.

Fixes #1896
