This PR adds support for optionally running pyodide in a web worker: - add a new option config.execution_thread, which can be `main` or `worker`. The default is `main` - improve the test machinery so that we run all tests twice, once for `main` and once for `worker` - add a new esbuild target which builds the code for the worker The support for workers is not complete and many features are still missing: there are 71 tests which are marked as `@skip_worker`, but we can fix them in subsequent PRs. The vast majority of tests fail because js.document is unavailable: for it to run transparently, we need the "auto-syncify" feature of synclink.
