Rename common directory to tooling

[michael-hawker]

Draft request to test CI, needs to wait for #403 to be merged first (and then this PR needs to be rebased).

This PR:

• moves common to tooling
• creates a ToolingDirectory property
• creates a couple of env in build.yml

Basically makes it easier to configure/change later without having to be hard-coded, but not completely yet. But enough while I was swapping many things out anyway.

Looks like I missed something somewhere:

Run ./tooling/GenerateAllSolution.ps1

Found it, not sure how that didn't show up in the rename I did... whatever

Error was the .NET Native memory one in the pipeline... need to rebase anyway, doing that now.

Approved, looks good as long as CI passes! Glad to see we parameterized the tooling directory as well 🙂

Awesome, thanks! Yeah, it's not completely parameterized yet, but figured I'd start us down that path, that way in the future eventually it'll just be something that's a prop variable somewhere or something and can be changed. At least until we get to a package or something setup instead.

Hitting CommunityToolkit/Tooling-Windows-Submodule#9 with this constantly for some reason, spun up #406 off main to see if that helps there at all...
