Updates the baseline used for the performance tests to 6.7, so that the theme is available in those test runs.

Remove TT5 from performance tests as the baseline tests run against an older version of WordPress that do not include all of the functions used in the new theme.
Follow up to [59146], [59150].

Simplifies the tests setup by leveraging a test matrix, improving maintenance and making it much easier to test more scenarios. With this change, tests are now also run with an external object cache (Memcached). Additional information such as memory usage and the number of database queries is now collected as well.
Improves test setup and cleanup by disabling external HTTP requests and cron for the tests, as well as deleting expired transients and flushing the cache in-between. This should aid the test stability.
When testing the previous commit / target branch, this now leverages the already built artifact from the build process workflow. Raw test results are now also uploaded as artifacts to aid debugging.

Adds new tests for localized sites as well as the dashboard.
Also amends Server-Timing output to measure memory usage in all scenarios.

As per the migration plan shared last year, this migrates all browser-based tests in WordPress core to use Playwright.
This includes end-to-end, performance, and visual regression tests.

Three new metrics are being collected and reported as part of this change:
- Time To First Byte (TTFB) - the time between the request for a resource and when the first byte of a response begins to arrive
- Largest Contentful Paint (LCP) — the render time of the largest image or text block visible within the viewport
- The difference between the two (LCP minus TTFB)

This adds a new GitHub Action workflow that measures a set of performance metrics on every commit, so we can track changes in the performance of WordPress over time and more easily identify changes that are responsible for significant performance improvements or regressions during development cycles.
The workflow measures the homepage of a classic theme (Twenty Twenty-One) and a block theme (Twenty Twenty-Three) set up with demo content from the Theme Test Data project. Using the e2e testing framework, it makes 20 requests and records the median value of the following Server Timing metrics, generated by an mu-plugin installed as part of this workflow:
- Total server response time
- Server time before templates are loaded
- Server time during template rendering
In addition to measuring the performance metrics of the current commit, it also records performance metrics of a consistent version of WordPress (6.1.1) to be used as a baseline measurement in order to remove variance caused by the GitHub workers themselves from our reporting.
The measurements are collected and displayed at https://www.codevitals.run/project/wordpress.
