* [executable semantics] class-ify Declaration NFC (no functional change). Proof of concept that we can simplify code by replacing unions with safer, more regular types. Hand-rolled existentials (type-erasing CoW wrappers) are a follow-on step that will further simplify usage. Began adding `const` where possible, and replacing `std::string*` with `std::string`. Most `const`s can disappear as we replace reference semantics with value semantics, but in the meantime it's an important step in the right direction.
