Enforce a hard limit for the size of images to be decoded

Although standards like JPEG allow for sizes as large as
65,535×65,535 pixels, we realistically cannot fit such large images in
memory.

Created a test gif since it's the smallest format I could find. It's
larger than strictly necessary for the test in case we want to increase
the hard limit in the future.

Bug: 444671303
Test: manually verified that a notification that causes a crashloop
without this change, doesn't anymore
Test: LocalImageResolverTest
Flag: EXEMPT CVE_FIX
