Generates a random context value for the placeholder tests.
The #context array used by the placeholder #lazy_builder callback will generally be used to provide metadata like entity IDs, field machine names, paths, etc. for JavaScript replacement of content or assets. In this test, the #lazy_builder callback PlaceholdersTest::callback() renders the context inside test HTML, so using any random string would sometimes cause random test failures because the test output would be unparseable. Instead, we provide random tokens for replacement.
