Migrate AzDo build, release pipeline to Github Actions

[tomjebo]

We currently have disabled PR triggered AzDo pipeline builds for security reasons.
To resolve this, we should create a Github Action based pipeline.

This issue should track the effort and discuss requirements, features needed, etc...

Current ability:

• Remove current AzDo build from PRs/etc
• Build/test all permutations of ProjectLoadStyle/os/configuration
• See test failures/output
• Build package
• Sign package
• Deploy package to CI feed on main
• Deploy package to NuGet on GitHub releases (we can probably use an event here so when we create a release, it will automatically push the package to NuGet)
• Verify package names are what we expect

Additional we can add:

• Benchmarks
• Code coverage

I've add a few of the requirements - are there others we want to make sure we do?

@tomjebo any reason this is still open? I think you can close it out
