Message:

Build/Test Tools: Overhaul performance tests to improve stability and cover more scenarios.

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.

Fixes #59900
