gh-109408: Move Windows builds from Azure Pipelines PR to GitHub Actions

[hugovk]

Situation now

There are two top-level pipelines on Azure Pipelines:

• Azure Pipelines CI (ci.yml) - run post-merge on version branches. This PR makes no changes to it.
• Azure Pipelines PR (pr.yml) - runs for PRs to main. This PR makes changes here.

The Azure Pipelines CI pipeline does this for Windows:

• Build and test for win32
• Build and test for win64
• Some layout tests

The Azure Pipelines PR pipeline does this for Windows:

• Build and test for win32
• Build and test for win64
• Build for arm64 (but not test because it would need to run on the same architecture)

GitHub Actions does this for Windows:

• Build and test for win32
• Build and test for win64

Changes in this PR

Azure Pipelines CI pipeline:

• Build and test for win32 (no change)
• Build and test for win64 (no change)
• Some layout tests (no change)

Azure Pipelines PR pipeline:

• Build and test for win32(removed)
• Build and test for win64(removed)
• Build for arm64(removed)

GitHub Actions:

• Build and test for win32 (no change)
• Build and test for win64 (no change)
• Add arm64 build(added)
  • Allowed to fail
• This now matches what Azure Pipelines PR did

Questions

@zooba Couple of questions:

• Would you like an arm64 build on Azure Pipelines CI? Edit: No
• Do we want the arm64 build on GitHub Actions? Edit: Yes

• Issue: Move Azure Pipelines CI to GitHub Actions #109408

[zooba]

I'm not sure my Azure credit will cover the full month, but I already have an ARM64 VM attached to AzDO that could run tests. It's used for the PGO training for releases, and I normally only run it for release builds.

But we already have buildbots, so those are fine for now. When we can enable an ARM64 test for free on either GHA or AzDO, then we can do it.
