Remove unnecessary Slack workflow runs for old branches

[desrosj]

In [51934], Slack notifications for GitHub Action workflows were restored for older branches. This was done by adding the workflow_run event to the Slack workflow in trunk, which restored notifications without having to backport anything.

While this works, one downfall of this method is a ​separate workflow run is created to send notifications for every qualifying workflow that completes. This means there are 2 workflows for every one that runs instead of 1.

It also makes it difficult to track which Slack workflow belongs to a normal workflow run.

The Slack workflow is a ​reusable one and when used this way, the notifications are done as a part of the original workflow. The 5.9 branch and newer have used it in this way instead on the workflow_run event, and it has worked well.

Let's backport this to the older branches to help limit the noise caused by excessive workflow runs and to simplify the Slack notifications workflow by eliminating any logic specific to the workflow_run event (which has data passed in different ways).

The original work for making the Slack notification workflow a reusable one was done as part of #53363, and initially introduced in [51921].

This removes the workflow_run event and any related logic from the Slack workflow. The changes required to use the workflow as a callable one in older branches are staged and ready to go. This will avoid having to create a separate workflow run to send Slack notifications for older branches.

Another thing to mention about using the Slack workflow as a reusable one is that the workflow is called from a specific branch, tag, or SHA. So future modifications to how the workflow works can be made once to trunk and will automatically apply to all older branches.

[desrosj]

In 53591:

Build/Test Tools: Remove the workflow_run event from the Slack notification workflow.

The workflow_run event was added to restore Slack notifications for older branches (5.8 and older) without having to backport any changes while alternate approaches were explored.

The workflow has been tested and refined as a reusable one in trunk, and this approach is superior to the workflow_run event in several ways.

Primarily, the workflow_run event results in a separate workflow run being created for sending Slack notifications after the completion of each workflow triggered by push. When called as a reusable workflow, this does not happen and the additional jobs are instead added to the initial workflow. This makes which jobs are sending notifications for the current workflow more clear, and reduces the amount of noise (less workflow runs overall).

The workflow_run event also makes some data available in different ways than push events. By removing it, much of the logic within the workflow can be simplified.

See #56095.

The Slack notification workflow will now be called as a reusable one, which has several benefits (see [53591]).

Several other minor GitHub Actions related updates are also being backported in this commit to maintain tooling consistency across branches that still receive security updates as a courtesy when necessary.

Workflows that are not relevant to this branch that were mistakenly backported are also being deleted.
