This will allow running Windows Containers to have their resource
limits updated through containerd. The CPU resource limits support
has been added for Windows Server 20H2 and newer, on older versions
hcsshim will raise an Unimplemented error.

Currently, there are few issues that preventing containers
with image volumes to properly start on Windows.
- Unlike the Linux implementation, the Container volume mount paths
were not created if they didn't exist. Those paths are now created.
- while copying the image volume contents to the container volume,
the layers were not properly deactivated, which means that the
container can't start since those layers are still open. The layers
are now properly deactivated, allowing the container to start.
- even if the above issue didn't exist, the Windows implementation of
mount/Mount.Mount deactivates the layers, which wouldn't allow us
to copy files from them. The layers are now deactivated after we've
copied the necessary files from them.
- the target argument of the Windows implementation of mount/Mount.Mount
was unused, which means that folder was always empty. We're now
symlinking the Layer Mount Path into the target folder.
- hcsshim needs its Container Mount Paths to be properly formated, to be
prefixed by C:. This was an issue for Volumes defined with Linux-like
paths (e.g.: /test_dir). filepath.Abs solves this issue.
