Add LCOW /dev/shm size runhcs option

[anmaxvl]

Add new const annotation AnnotationLCOWDevShmSizeInKb for setting the
default size for /dev/shm in LCOW scenarios. Replace existing hardcoded
references with the new const. Overwrite container spec whenever the
annotation is present.

Depends on #1201

Well this is sad, it seems to be crying because you're using the oci package in the guest and it pulls in some other imports that are Windows only?

that's what it looks like... even though there're no explicit build tags present. welp

Be good to see if we can screw with build tags enough or fix some things so we can import /internal/oci in /internal/guest but lgtm

I thought about doing some refactor and potentially export the annotations somewhere. I think we use hardcoded annotations in CRI/containerd forks/upstream as well.

I'm fine with moving the annotations to their own package if that helps here

opened a separate PR to address this #1201

Why do we want this in the runhcs options?

This is a shortcut to enable workloads for one of our customers. The annotations approach is taking too much time to plumb through the entirety of our stack.

closing in favor of #1210
