ci: Consolidate PR workflows

[jamesnrokt]

Background

• Currently we have many workflows that are triggered by a pull request
• This PR consolidates them into a single file while allowing them to be called individually with workflow_dispatch, allowing developers to test as needed before opening their PR
• Finally the notification is now sent only once everything passes instead of just after a simple build job
• This provides a quick overview of test progress without clicking into many workflows

What Has Changed

• Github Actions workflows
