This backports several build and test tool improvements to the 5.6 branch. Most notably, this includes:
- The changes required to allow each workflow to be triggered by the `workflow_dispatch` event so that tests can be run on a schedule [50590].
- The ability to run PHPUnit tests from `src` instead of `build` [50441-50443].
- Splitting single site and multisite tests into parallel jobs [50379].
- Split slow tests into separate, parallel jobs for PHP 5.6 [50444].
- Better branch and path scoping for GitHub Action workflows when running on `pull_request` [50432,50479].
- Several `devDependency` updates.
