Broker: Add ability to pass parent window handle explicitly for Windows broker auth

[seclerp]

We have a headless process that hosts the NuGet credential plugin manager and we are facing issues with the default broker logic which tries to obtain the current process' window handle, as we need to pass a native window handle of another (non-.NET) desktop app process. I think the change will be quite beneficial in such a scenario.

I'm open to discussion in case env-based handle propagation is not the best approach.

I have a question - what is a proper workflow for internationalization? Should I update the default Resources.resx only?

Hi @embetten, do you need something else from my side, any concerns? Is there something that prevents this stuff from being merged?

Currently this is not localized. Any strings to be logged should be added there so they will be localized in the future ( #464 )

Conflict resolutions would be appreciated. The only blocker was our internal validation.
