Implement ImageBitmapOptions resize

In this CL, we add the options resizeWidth && resizeHeight &&
resizeQuality to the ImageBitmapOptions. All these options are hidding
behind the experimtanl flag.

Also, this CL implements this options for creating an ImageBitmap from
HTMLImageElement, HTMLCanvasElement, ImageBitmap and Blob. For creating
an ImageBitmap from ImageData and HTMLVideoElement is a bit more
complicated and will finish that in a separate CL.

This CL also adds a layout test to ensure the correctness of the behavior.
