Fixes: dotnet/dnceng#5645

We switch to Azure Linux for x64 some months ago. We're now doing the same for Arm64.

I changed all the definitions (that I found). We want to see any failures if they exist.

Pull Request Overview

This PR switches Helix VM hosts from Ubuntu 22.04 to Azure Linux 3 for ARM64 architectures across the dotnet/runtime CI pipeline. This change aligns ARM64 builds with the x64 migration to Azure Linux that was completed months earlier.

Key changes:

  • Replace Ubuntu.2204.ArmArch hosts with AzureLinux.3.ArmArch hosts for ARM32 and ARM64 platforms
  • Update Helix queue configurations across libraries, installer, and CoreCLR pipelines
  • Minor capitalization fix for Alpine.Edge reference

We have started seeing a lot of timeouts on Arm64 after this was merged. For example, the following legs timed out in #117857 :

Do we need to increase Azure Linux Arm64 Helix VM capacity to accommodate this change?

If we cannot resolve this by EOD we should revert the change. If we already know that we cannot resolve this by EOD we should revert it now. Anyone can do that.
