This PR separates a `Value` sort for `Union` out of `Aggregate` as there are different semantics for the projections (and it also makes the code clearer). A `Union` has one argument which is data, but it can be interpreted as different types via field projections - this is significantly different from other field projections that access different data via different arguments. Currently the implementation only supports accessing fields of the same type as the `Union` construction (no switching between types right now).
This PR brings into the K AST the fields and layout of unions that were updated in #854 which is the stable-mir-json update runtimeverification/stable-mir-json#105
