canvas: Add HTMLVideoElement to CanvasImageSource union type (#37135)

Follow to the specification and add HTMLVideoElement to
CanvasImageSource union type
to allow use it as image source for createPattern/drawImage operations.
https://html.spec.whatwg.org/multipage/#canvasimagesource

https://html.spec.whatwg.org/multipage/#dom-context-2d-createpattern
https://html.spec.whatwg.org/multipage/#dom-context-2d-drawimage

The HTMLVideoElement media resource has an associated origin:
- media provider object (MediaStream/MediaSource/Blob): CORS-same-origin
 - URL record: CORS-cross-origin/CORS-same-origin

https://html.spec.whatwg.org/multipage/media.html#media-resource

Testing:
 - html/canvas/element/*
 - html/semantics/embedded-content/the-canvas-element/*
