Introduce a "@box T" type for SIL. Represents a heap allocation containing a value of type T, which we'll be able to use to represent the payloads of indirect enum cases, and also improve codegen of current boxes, which generates non-uniqued box metadata on every allocation, which is dumb. No codegen changes or IRGen support yet; that will come later. This time, fix a paste-o that caused SILBlockStorageTypes to get replaced with SILBoxTypes during type substitution. Oops.
