Convert pipelines to GitHub Actions

[bart-vmware]

Description

Adds GitHub Actions workflows for Steeltoe.All and Sonar. PR diff coverage is reported by Sonar, full branch coverage in a PR comment (summarized) and in the build summary (detailed).
Fixes the upload of crash/hang dumps during test runs.
Removes old Azure DevOps pipelines.

Packaging still uses Azure DevOps, to be addressed in a subsequent PR.

Note

This PR contains reverted commits to test various kinds of scenarios.

• Consider standardizing OS identifiers across workflows; using 'macos' here may be inconsistent with other workflows that reference 'macos-latest' or 'macOS'.

      if: ${{ inputs.OS == 'macos' }}
