Consideration to offer ClangSharpPInvokeGenerator as .NET Core global tools

[dotChris90]

Hello Clang-Team,

hope you still looking into this repo :D

In my opinion it would be a nice idea to offer your very interesting ClangSharpPInvokeGenerator as a .NET Core global tool.

People using .NET Core simple can download it from NuGet and do sth like dotnet pinvoke ./myNativeCode . Finish.

I am not sure if you think the same way but just wanted to let you know ;)

Greetings

Going to close this in favor of #46 (which tracks the same thing).

I'm going to get #72 and a follow-up PR merged and then I plan on getting new preview packages published, which includes ClangSharpPInvokeGenerator as a global tool.
