In preparation for shifting from `TypeId`s potentially representing attached types to always representing unattached types, using [terminology suggested on Discord](https://discord.com/channels/655572317891461132/963846118964350976/1359286326779973712). This change causes us to track slightly more type spelling information through SemIR. One change that has significant impact on the SemIR output is that we now build a `struct_type` instruction in each class representing the types of the fields, including the spelling used for those types. This is now no longer always identical to the corresponding canonical `struct_type` for the object representation, so it's built separately and owned by the class. Also remove `TypeBlock` support entirely, as its only use was representing `TupleType`s, which now use an `InstBlock`.
