imagebitmap: Add missing basic functionality (#37025)
Add missing basic functionality for ImageBitmap https://html.spec.whatwg.org/multipage/#imagebitmap including new variant of creation bitmap with source rectangle https://html.spec.whatwg.org/multipage/#dom-createimagebitmap but without support of cropping bitmap data with formatting. Add ImageBitmap to CanvasImageSource union type https://html.spec.whatwg.org/multipage/#canvasimagesource Add ImageBitmap to TexImageSource for WebGL https://registry.khronos.org/webgl/specs/latest/1.0/index.html Testing: Improvements in the following WPT tests - html/canvas/element/manual/imagebitmap/* - html/canvas/element/manual/wide-gamut-canvas/* - html/semantics/embedded-content/the-canvas-element/* - webgl/tests/conformance/textures/image_bitmap_from* - webmessaging/postMessage_cross_domain_image_transfer_2d.sub.htm Fixes: https://github.com/servo/servo/issues/34112 Signed-off-by: Andrei Volykhin <andrei.volykhin@gmail.com>
