This attempts to reland the single-threaded Skwasm PR: https://github.com/flutter/engine/pull/56206 The main changes here are in the second commit: * We need to actually bundle the `skwasm_st` artifacts in `flutter_web_sdk.zip` * The `locateFile` hack no longer works since emscripten doesn't actually create a worker.js file anymore. So instead, that has been modified to use the `mainScriptUrlOrBlob` module API to do a very similar hack. Note: I did presubmit testing with the framework CI and it appears the pertinent tests pass. See https://github.com/flutter/flutter/pull/157967
