Enforce code styling and editor config

[Arlodotexe]

The Labs repo is using default settings for code styling and .editorconfig. We need to bring in the .editorconfig and other code styling analyzers from the main repo.

Reading more, looks like .editorconfig should handle most of our needs these days. It should be able to specify stuff in the IDE, but also in our CI.

Info on running XAML Styler on commit here as well: https://github.com/Xavalon/XamlStyler/wiki/Git-Hook

Looking at seeing if I can add this stuff in, so assigning to myself.

Investigated looking at a tools manifest to help us with things: https://docs.microsoft.com/en-us/dotnet/core/tools/local-tools-how-to-use

And of course the Git Hooks docs: https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks

Though running into some issues getting it to run.
