This commit:
* Removes the PHPUnit 7 specific `TestCase`.
* Removes all existing polyfills from the PHPUnit 5.x `TestCase`.
* Imports all polyfill traits from the PHPUnit Polyfills package into the `WP_UnitTestCase` class and updates the DocBlock to reflect the actual function of the class.
* Note: The list of polyfills needs to be verified and updated after each new release of the PHPUnit Polyfills package. Alternatively (recommended), one of the built-in `TestCase` classes from the PHPUnit Polyfills package can be used instead.
* Moves the `require` for the WP `abstract-testcase.php` to the `bootstrap.php` file.
* Adds a `require_once` for the PHPUnit Polyfills autoloader to the `bootstrap.php` file.
* Note: while this isn't _strictly_ necessary when the tests are run via Composer, having the include in the bootstrap allows for the tests to also be run via a PHPUnit Phar, providing contributors with more flexibility.

The PHPUnit Polyfills package is an add-on for PHPUnit, which works around common issues for writing PHPUnit cross-version compatible tests.
Features:
* It offers a full set of polyfills for assertions and expectations introduced in PHPUnit since PHPUnit 4.8.
* It offers two generic TestCases which include these polyfills, but also solve the `void` return type issue for the fixtures methods.
* It offers a PHPUnit cross-version solution for the changes to the PHPUnit `TestListener` implementation.
* Supports PHPUnit 4.8 – current.
* Supports and is compatible with PHP 5.4 – current.
The package has no outside dependencies, other than PHPUnit, is actively maintained and endorsed by the maintainer of PHPUnit itself (the only package of its kind which has ever been endorsed).

Since branch filtering happens prior to the workflow run being created, filtering the branches that `workflow_run` will fire on for this workflow should cut down on the number of skipped “Slack Notifications” runs listed in the Actions section of the repository.
This also removes the check for a `skipped` outcome in the requesting workflow. Workflows for push events resulting from WordPress Core commits are never skipped.

Previously the tests were run via a PHPUnit Phar file for PHP 5.6–7.4, with PHP 8.0 using a Composer-installed version of PHPUnit.
Running the tests via a Phar without the need for a `composer install` is (marginally) faster in overall build time, however, this commit is part of a larger chain of changes which will make the test suite PHPUnit cross-version compatible.
With an eye on those upcoming changes, which will allow us to run the tests on the most appropriate PHPUnit version for each supported PHP version, it is opportune to switch to using a Composer-installed version of PHPUnit for all PHP versions supported by WordPress. Previously this was not possible without additional conditional `update` commands being run, due to the `composer.lock` file being in place and being locked at PHPUnit 7.5.20.
Switching over to using the Composer-installed PHPUnit version, with that PHPUnit version adjusting based on the PHP version, allows for some minor simplifications in the GitHub Actions script.
This means we need additional measures to make sure that the Composer cache file does not go too far out of date as that would significantly slow down the builds.
By adding a "Last Monday" date to the cache key, in combination with the pre-existing OS, PHP version and the hash of the `composer.json` file, we can guarantee that:
1. There will be a cache created for each OS/PHP combination.
2. These caches will be replaced whenever a change is made to the `composer.json` file.
3. These caches will be replaced every Monday of each week ensuring that the cache file does not go too far out of date.
Note: The NPM script `test:php` is now no longer needed during the builds. However, to prevent breaking the workflow of contributors who may be used to having the command available, the command remains available.
In a future iteration we may be able to replace the caching of the Composer dependencies with the Composer cache action as offered on the GitHub marketplace, which would further simplify the script.

This prevents the classes from being loaded automatically via the `autoload-dev` directives when a Composer-installed PHPUnit 5.x or 6.x version is used, as that would break the test run.
It is expected that this autoloader will be removed soon, as it should no longer be needed when the PHPUnit version constraints are widened.
Notes:
* The autoloader file will be loaded from the Test bootstrap.
* The autoloader will always be registered and directed to queue itself _before_ the Composer autoload file (which will already have been registered).
* The autoloader will only actually load the WP copies of the files/classes when PHP 8.0 in combination with PHPUnit 7.x is detected. In all other cases, the autoloader will bow out, which effectively then defers to the Composer autoload file to load the files as shipped with the installed PHPUnit version.

This makes it easier to run unit tests against multiple different PHP versions.
There is currently no reason to have a `composer.lock` file as:
* External runtime dependencies are not managed via Composer.
* Managed updates of the non-runtime dependencies can be done by locking the version used in the `composer.json` file to a precise version instead of using a `composer.lock` file.
* Having the `composer.lock` file in place makes it a lot more difficult to run the tests against all supported PHP versions.
With these considerations in mind, the lock file is now removed from version control and added to `.gitignore` and `svn:ignore`.
Version constraints for the current dev dependencies are adjusted accordingly:
* PHPUnit now explicitly declares in its version constraints that PHPUnit 5.x, 6.x, and 7.x are supported. The minimum supported version for PHPUnit 5.x has been raised from 5.4 to 5.7, which in practice was already the version used for running the tests on PHP 5.6.
* PHPCompatibilityWP is effectively updated to version 2.1.2 with the positive impact that a few new constants polyfilled in WP 5.8 are now accounted for (excluded from being flagged).
* PHP_CodeSniffer is declared as an explicit dependency to ensure that updates to it will always be explicitly managed instead of inherited.
* The DealerDirect Composer plugin is effectively updated to version 0.7.1 without impact.

This expands Slack notifications to include success, cancelled, and “fixed” GitHub Action workflow run outcomes in addition to failures.
A “fixed” outcome occurs when the previous run for a workflow failed and the current one succeeds. This matches the behavior that was native to TravisCI by setting `on_success` for notifications to `change`.
The message details and where each outcome is posted is controlled by Slack workflows.
The Slack notification logic has also been pulled into a separate workflow to prevent repeating code in every workflow.

This avoids a "Table `wp_options` doesn't exist" database error when trying to create a nonce for password reset button.
When installing and using database-saved salts, `wp_create_nonce()` causes database errors as `wp_salt()` attempts to insert into the not-yet-created options table. Since authentication is not available during installation, we can safely skip creating a nonce.

This relates to the [https://wiki.php.net/rfc/internal_method_return_types Return types for internal methods RFC] in PHP 8.1 and in particular, the change made in [https://github.com/php/php-src/pull/7051 PHP PR #7051], which adds a `mixed` return type to the `JsonSerializable::jsonSerialize()` interface method.
WordPress only contains one (test) class which implements the `JsonSerializable` interface and this commit fixes the issue for that class.
As of PHP 8.1, the `jsonSerialize()` method in classes which implement the `JsonSerializable` interface are expected to have a return type declared. The return type should be `mixed` or a more specific type. This complies with the Liskov principle of covariance, which allows the return type of a child overloaded method to be more specific than that of the parent.
The problem with this is that:
1. The `mixed` return type was only introduced in PHP 8.0.
2. Return types in general were only introduced in PHP 7.0.
WordPress still has a minimum PHP version of 5.6, so adding the return type is not feasible for the time being.
The solution chosen for now is to add an attribute to silence the deprecation warning. While attributes are a PHP 8.0+ feature, due to the choice of the `#[]` syntax, in PHP < 8.0, attributes will just be ignored and treated as comments, so there is no drawback to using the attribute.

It aligns with the changes proposed added in Gutenberg: https://github.com/WordPress/gutenberg/pull/33293.
The idea here is to split the growing webpack config into two parts: blocks and packages.
We need to add handling for JavaScript files that are going to be used with blocks on the frontend. They didn't work quite well with the current setup for entry points created for packages.
As part of the effort, it adds support for `viewScript` in `block.json` metadata file that is later translated to `$view_script` in `WP_Block_Type` class and exposed as `view_script` from the REST API endpoint for block types.
