Support guest tools updates on Windows again (for ARM also)

[mattlqx]

Looks like at some point PTIAgent.exe was removed from the Parallels Desktop app bundle and so this plugin updating tools on Windows no longer works.

The current tools distribution for Windows is via ISOs in the app bundle now just as Linux and Mac are. We can copy the ISO and mount it with Powershell, then execute the updater.

Tested this with Parallels 19 and Windows 11 22h2 image with an outdated tools from earlier 19.x releases.

And when it came back up, tools install was good.
