This commit teaches to compiler to update its world bounds whenever it looks at a binding partition, making the compiler sound in the presence of a partitioned binding. The key adjustment is that the compiler is no longer allowed to directly query the binding table without recording the world bounds, so all the various abstract evaluations that look at bindings need to be adjusted and are no longer pure tfuncs. We used to look at bindings a lot more, but thanks to earlier prep work to remove unnecessary binding-dependent code (#55288, #55289 and #55271), these changes become relatively straightforward. Note that as before, we do not create any binding partitions by default, so this commit is mostly preperatory.
