function BigPipeRegressionTest::doInlineScriptTest

Tests for the correct replacement of a chunk with inline javascript.

Parsing a <script> tag causes a mutation to be reported because it triggers a micro task checkpoint. Watching for template tags directly results in early mutation reporting, and the trailing markup is not yet parsed when the template is processed.

Also, chunk markup needs to not be double escaped. We encountered both regressions in https://www.drupal.org/project/drupal/issues/3526267.
