Create an installer for windows to replace the use of chocolatey

[IsaacPD]

At the moment skaffold is not able to properly clean up because of the behaviour of chocolatey as tracked in #4815. This behavior is important to skaffold and should not be compromised to use chocolatey. In order to replace the functionality chocolatey provides, a windows installer should be provided that accomplishes what chocolatey provides, namely installing to PATH and updating.

Let's discuss in triage

I have got some code that is able to create an installer using NSIS here https://github.com/IsaacPD/skaffold/tree/nsis-windows-installer

The installer can:

• Install to a user specified directory
• Add that directory to the user's PATH
• Uninstall skaffold and remove that directory from their path

There is also support to install additional files as is common on windows installers if we are interested on that.

Preference has shifted to using NSIS instead of WIX because it can be built on platforms other than windows. Thanks to @briandealwis for bringing NSIS to my attention.

It seems like we may be better off integrating with Windows Package Manager.
