Fix CI for MW master compatibility

- Use per-matrix search engine images: Elasticsearch 7.10 for
  REL1_43–REL1_45, OpenSearch 1.3 for master (CirrusSearch dropped
  Elasticsearch support on master)
- Handle MW master's removal of tests/phpunit/phpunit.php by falling
  back to composer phpunit
- Download phpunit.xml.template in install script since GitHub tarballs
  exclude it via .gitattributes export-ignore
- Stop using removed SpecialPageTestBase, extend
  MediaWikiIntegrationTestCase directly
- Pass PageIdentity instead of LinkTarget to getRevisionByTitle
  (deprecated since MW 1.36, enforced on master)
- Bump cache key version and mark master as non-experimental
