Add 'dotnet new' templates for NoTargets and Traversal

MattKotsenas commented 7 months ago

Fixes #472

Add two new projects: Microsoft.Build.NoTargets.Templates and Microsoft.Build.Traversal.Templates that each publish a NuGet package that can be installed / used via dotnet new.

I wasn't quite sure how best to structure the project, so feedback is appreciated. Some things to consider:

The template projects currently live under their respective "feature" folders. It's also common to create a top-level "Templates" folder like this, however that breaks the package-per-feature pattern currently used in the repo.
- Additionally, currently the templates folder is a child of the main project in the source tree, but they're more conceptually siblings. If there's a different arrangement that makes more sense to people let me know.
Currently the version for the template packages match the version of the SDK package. I think that makes sense, but if they should be versioned independently I can make that change as well.
The NoTargets template uses the .msbuildproj extension. If we should use .proj, or if there's a better extension to use please let me know.
I added several comments to help new users, but there may be so much that it's annoying for experienced users. Editing feedback welcome.
In order to keep the NoTargets template consistent with the README, I changed the TargetFrameworkVersion in the README from net462 to netstandard2.0, since that's compatible with both .NET Framework and .NET, and still supported (basically) everywhere.

Friendly ping here. I fully expect this review to take a couple of rounds to get the directory layout the way maintainers want, so any help / guidance is very appreciated. Thanks!

Just FYI discussing this internally with the MSBuild team. I want to make sure this aligns with their vision before we make this change. Sorry for the delay!
