Move `pkg/cri/opts.WithoutRunMount` function to `oci.WithoutRunMount`
so that it can be used without dependency on CRI.
Also add `oci.WithoutMounts(dests ...string)` for generality.

This enables cases where devices exist in a subdirectory of /dev,
particularly where those device names are not portable across machines,
which makes it problematic to specify from a runtime such as cri.
Added this to `ctr` as well so I could test that the code at least
works.

This change is needed for running the latest containerd inside Docker
that is not aware of the recently added caps (BPF, PERFMON, CHECKPOINT_RESTORE).
Without this change, containerd inside Docker fails to run containers with
"apply caps: operation not permitted" error.
See kubernetes-sigs/kind 2058
NOTE: The caller process of this function is now assumed to be as
privileged as possible.

The Err() method should be called after the Scan() loop, not inside it.

With the change in #3542 it breaks $PATH handling for images becuase our
default spec always sets a PATH on the process's .Env.
This removes the default and adds an Opt to add this back.

1. Fixes bugs in ctr run that were introduced by 1d9b969
2. Adds support for the --isolated flag that runs Windows HyperV
cotainers instead of process isolated containers on Windows.

If we are using an image config, we should by default add any additional
GIDs that are found from reading /etc/group, even if the default user is
root.

Add flag and With-helper to set NoNewPrivileges to false since it is on
by default in the default UNIX spec for containerd, but off by default
in Docker and CRI plugin use. This allows for easy testing with it off
for comparison.

When creating a default OCI spec on Windows that is targeting the LCOW
platform it needs to contain a Windows section as well. This adds the
Windows section by default. It also protects against this case for all
OCI creation that doesnt use the OCI package in the runhcs-shim.

On Windows we need to be able to create both Linux and Windows OCI spec
files by default to support WCOW and LCOW scenarios. This merges the
compile time differences into runtime differences between the two based
on the spec and platform the user sets.
It maintains the old behavior with Default specs resulting in the
platform default the binary is compiled for.

We introduce a WithSpecFromFile option combinator to allow creation
simpler creation of OCI specs from a file name. Often used as the first
option in a `SpecOpts` slice, it simplifies choosing between a local
file and the built-in default.
The code in `ctr run` has been updated to use the new option, with out
changing the order of operations or functionality present there.

In a few places we check for nil types when modifying a spec,
but in many cases we do not so we could get a panic if the
passed in type was not filled. Because the generated spec is
filled we will not notice this but users may get unexpected
panics.
