pixels: Move Snapshot and related data structures to pixels (#37590)

Browse source 
1. The `shared` directory is for the "_traits" crates, which will likely
   be moved out of this directly at some point and renamed "_api". These
   crates expose the API of crates to avoid circular dependencies.
   `Snapshot` isn't really this.
2. `Snapshot` is essentially a specialied kind of `Image` so it makes
   sense that it is grouped with other image-related things in `pixels`.

Testing: This should not change any behavior so is covered by existing
tests.
