[CodeGen, CHERI] Add capability types to MVT. (#156616)
This adds value types for representing capability types, enabling their use in instruction selection and other parts of the backend.
These types are distinguished from each other only by size. This is sufficient, at least today, because no existing CHERI configuration supports multiple capability sizes simultaneously. Hybrid configurations supporting intermixed integral pointers and capabilities do exist, and are one of the reasons why these value types are needed beyond existing integral types.
