gpui: Add support for animated images (#13809)

This PR adds support for animated images. The image requires a id for it
to actually animate across frames.

Currently it only has support for `GIF`, I tried adding decoding a
animated `WebP` into frames but it seems to error. This issue in the
image crate seems to document this
https://github.com/image-rs/image/issues/2263.

Not sure if this is the best way or the desired way for animated images
to work in GPUI but I would really like support for animated images.
Open to feedback.
