[HTML-in-Canvas] Implement the IDL changes for HTML-in-Canvas
https://bugs.webkit.org/show_bug.cgi?id=320677
rdar://183661820
Reviewed by Simon Fraser.
This change implements the IDL additions which are required for
HTML-in-Canvas[1].
The WebCore sources were changed just to allow compiling. New functionalities
will
be filled later. Here is the summary of this change:
1. The attribute layoutSubtree is added to HTMLCanvasElement. This attribute
will
force the layout for the canvas children.
2. The interface ElementImage is added. It represents a the drawing of an
Element
into a DisplayList
3. The event Paint is added. This event will fire any time, a canvas child is
repainted.
4. The ElementImage drawing functions to HTMLCanvasElement, OffscreenCanvas,
WebGL
and WebGPU are added.
5. Capturing a canvas child Element to ElementImage is added.
