As part of the effort of getting hypervisor isolated windows container
support working for the CRI entrypoint here, add the runhcs-wcow-hypervisor
handler for the default config. This sets the correct SandboxIsolation
value that the Windows shim uses to differentiate process vs. hypervisor
isolation. This change additionally sets the wcow-process runtime to
passthrough io.microsoft.container* annotations and the hypervisor runtime
to accept io.microsoft.virtualmachine* annotations.
Note that for K8s users this runtime handler will need to be configured by
creating the corresponding RuntimeClass resources on the cluster as it's
not the default runtime.

It is follow-up of #7254. This commit will increase ReadHeaderTimeout
from 3s to 30m, which prevent from unexpected timeout when the node is
running with high-load. 30 Minutes is longer enough to get close to
before what #7254 changes.
And ideally, we should allow user to configure the streaming server if
the users want this feature.

`ioutil` has been deprecated by golang. All the code in `ioutil` just
forwards functionality to code in either the `io` or `os` packages.

All of the CRI store related packages all use the standard errdefs
errors now for if a key doesn't or already exists (ErrAlreadyExists,
ErrNotFound), but the comments for the methods still referenced
some unused package specific error definitions. This change just
updates the comments to reflect what errors are actually returned
and adds comments for some previously undocumented exported functions.

All containers except the pause container, mount `/dev/shm" with flags
`nosuid,nodev,noexec`. So change mount options for pause container to
keep consistence.
This also helps to solve issues of failing to mount `/dev/shm` when
pod/container level user namespace is enabled.
Fixes: #6911

This's an optimization to get rid of redundant `/dev/shm" mounts for pause container.
In `oci.defaultMounts`, there is a default `/dev/shm` mount which is redundant for
pause container.

The TestPodAnnotationPassthroughContainerSpec test and the
TestContainerAnnotationPassthroughContainerSpec test both depend on a
platform-specific implementation of criService.containerSpec, which is
unimplemented on FreeBSD.
The TestSandboxContainerSpec depends on a platform-specific
implementation oc criService.sandboxContainerSpec, which is
unimplemented on FreeBSD.
