[Web] Allow specifying the strategy on when to use <img> element to display images (#159917)
This PR follows the discussion under
https://github.com/flutter/flutter/pull/157755 and adds a flag to
determine when `<img>` elements are used. By default the feature is
turned off.

Instead of just a boolean for on & off, I made it an enum to accept
multiple options. Notably, an `always` option can be useful when the
developer wants a unified experience regardless of the image origin
(such as when displaying an image from arbitrary URLs.)
