        Add v8 bindings for async DB API in workers
        https://bugs.webkit.org/show_bug.cgi?id=39145

        No new tests.  This should share layout tests with JSC.

        Tweak the callback generation to switch lots of Frame* to ScriptExecutionContext*, and use the context passed in to handleEvent where possible.
        * bindings/scripts/CodeGeneratorV8.pm:

        As with CodeGeneratorV8; these are pretty much all tiny tweaks.
        We do have to use a slightly different patch for callback invocation in invokeCallback, as V8Proxy::retrieve() doesn't work in the worker context.

        * src/DatabaseObserver.cpp:
        We should check that we're on the context thread now, not the main
        thread.
