The main changes here are: - Introducing `InitForm` and `RefForm` to represent initializing and reference forms (the two return forms currently supported by the parser). - Introducing the `FormType` singleton inst to represent their type (i.e. `Core.Form`). - Emitting an inst representing a function's declared return form as part of handling the function signature. The return form inst is currently ignored. Subsequent PRs will expose it in `SemIR::Function` and use it to determine the form of call expressions.
