Add support of the ImageBitmapRenderingContext as "bitmaprenderer" canvas context mode to RenderingContext/OffscreenRenderingContext https://html.spec.whatwg.org/multipage/#imagebitmaprenderingcontext It is initial implementation with public interface API but without any display presentation support for HTMLCanvasElement. Testing: Improvements in the following tests: - html/canvas/element/manual/imagebitmap/createImageBitmap-origin.sub.html - html/canvas/offscreen/manual/text/canvas.2d.offscreen* - html/canvas/offscreen/manual/the-offscreen-canvas/offscreencanvas.transfer.to.imagebitmap.nocrash.html - imagebitmap-renderingcontext/* Signed-off-by: Andrei Volykhin <andrei.volykhin@gmail.com>
