- Add a buildShims task to build_tasks.js that, for each chunk, creates a correspondingly-named build/<chunk>.mjs that will either (in uncompressed mode) import and reexport that chunk's entry point module (e.g. core/blockly.js) or (in compressed mode) load dist/<chunk>_compressed.js using a <script> tag and then export the corresponding properties on the chunk's exports object. - Provide helper methods used by these shims in tests/scripts/loading.mjs, including code to detect whether to load in compressed or uncompressed mode. - Add a quote() function to scripts/helpers.js, used by buildShims. This is copied from tests/bootstrap_helper.js, which will be removed in a later commit.
