Expands the test matrix used for testing on Windows to cover the three
connection plugins we support for all the tasks. This change also
changes how raw commands are run over SSH to avoid starting a
`powershell.exe` process that was uneeded in the majority of cases used
in Ansible. This simplifies our code a bit more by removing extra
Windows specific actions in the ssh plugin and improves the efficiency
when running tasks.
