Sam Clegg 505cccb9e9 [d8] Update new Worker API to match the Web API
Previously we only supported strings and not filenames.  This
changes the default to filename and adds a new `type: string` which can
be passed `options` to allow for strings to be passed in test code.

See: https://developer.mozilla.org/en-US/docs/Web/API/Worker/Worker
