Subject: feat(ext/web): add ImageData Web API (#21183)

Fixes #19288

Adds the `ImageData` Web API.

This would be beneficial to projects using `ImageData` as a convenient
transport layer for pixel data. This is common in Web Assembly projects
that manipulate images. Having this global available in Deno would
improve compatibility of existing JS libraries.
