chore: Updating workflows for code quality and testing integration

[colinmurphy]

Description

This solves a few issues

1. Splits code quality and testing integration into 2 steps
2. The first step is to check that the plugin has configuration files required to run the checks/tests
3. Instead of failing the whole action, we only run step 2 (code quality checks, tests) if they have the correct configuration
4. We also create specific actions so we can use these for badges

Outcomes are:

1. Reduces checks for plugins which might not have these checks/steps setup
2. Run plugin specific actions e.g. "hwp-previews php code quality checks"
3. We can then use this for each plugin

e.g.

[![Testing Integration](https://img.shields.io/github/check-runs/wpengine/hwptoolkit/main?checkName=hwp-previews%20codeception%20tests&label=Automated%20Tests)](https://github.com/wpengine/hwptoolkit/actions)

[![Code Quality](https://img.shields.io/github/check-runs/wpengine/hwptoolkit/main?checkName=hwp-previews%20php%20code%20quality%20checks&label=Code%20Quality%20Checks)](https://github.com/wpengine/hwptoolkit/actions)
