Message:

Build/Test Tools: Backport GitHub Action and build improvements to the 5.5 branch.

This backports several build and test tool improvements to the 5.5 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.

Merges [50267,50299,50379,50387,50413,50416,50432,50435-50436,50441-50444,50446,50473-50474,50476,50479,50485-50487,50545,50579,50590,50592,50598] to the 5.5 branch.
See #50401, #51734, #51801, #51802, #52548, #52608, #52612, #52623, #52624, #52625, #52645, #52653, #52658, #52660, #52667, #52786.

-     *
-     * The previous test confirms that no ampersands exist in src/wp-includes/js/wp-embed.js.
-     * However, we must also confirm that UglifyJS does not add ampersands during its
-     * optimizations (which we tweak to avoid, but indirectly -- understandably, there's
-     * no "don't add ampersands to my JavaScript file" option).
-     *
-     * So this test checks for ampersands in build/wp-includes/js/wp-embed.min.js.
-     * In many cases, this file will not exist; in those cases, we simply skip the test.
-     *
-     * So when would it be run? We have Travis CI run `npm run test` which then runs, in order,
-     * `qunit:compiled` (which runs the build) and then `phpunit`. Thus, this test will at least be
-     * run during continuous integration.
-     *
-     * However, we need to verify that `qunit:compiled` runs before `phpunit`. So this test also
-     * does a cheap check for a registered Grunt task called `test` that contains both
-     * `qunit:compiled` and `phpunit`, in that order.
-     *
-     * One final failsafe: The Gruntfile.js assertion takes place before checking for the existence
-     * of wp-embed.min.js. If the Grunt tasks are significantly refactored later, it could indicate
-     * that wp-embed.min.js doesn't exist anymore. We wouldn't want the test to silently become one
-     * that is always skipped, and thus useless.
