test images: Adds multiple Windows channels support

Browse Source 
This commit adds support for building test images for multiple
Windows versions, as we have to support both LTS and SAC channels.

With this, the format for Windows images in the BASEIMAGE files is:

OS/ARCH/OS_VERSION

Also adds --isolation-hyperv to the Windows docker build command, making sure
that container images for multiple OS versions can be built using the same
Windows node.
