Reverts #26074

Fixes flutter/flutter#82447

I think I have an alternative approach that won't need this. Unfortunately, we sometimes get hit with a large bump for the dart wrapper association, and addPicture is a very common call.

We should probably try to figure out why that happens and see if there's anything that can be done, but my suspicion is that it's due to thread contention and introducing more calls into the VM that allow for descheduling.

My alternative plan isn't doing great - I may end up trying to reland this after I better understand what's happening.
