OffscreenCanvas conformance tests: clean up and add new tests (#4281)

This pull request does three things:
1. Clean up some tests. In our previous pull requests, there were some tests that are wrong, mostly because typos, and some don't make sense.
2. Add image-smoothing tests, replicated from 2dcontext/
3. Add some tests for general OffscreenCanvas APIs, for example, commit(), transferToImageBitmap, and so on.

Notice that for some of the "general API" tests, the name of the worker tests ends with w.html. The reason is that we cannot name is with worker.html, otherwise the wpt test runner will automatically looking for a associated .js file which we don't have.
