Add more layout test cases to createImageBitmap

Add more layout test cases to createImageBitmap

Comparing Firefox's layout tests against Chrome's, we find that there are
two cases that is currently missing in our code base.

1). createImageBitmap from a neutered ImageBitmap.
2). createImageBitmap from a Blob object that is created by canvas.toBlob

This CL adds these two test cases.

As discussed on blink-dev, there may be concurrency issues in doing this in a
worker, would be nice to have tests that call all the flavors of
createImageBitmap from a worker. But that should be in a separate CL (when you
expose ImageBitmapFactories to workers)
