Switch TypeId::TypeType to TypeType::SingletonTypeId, and similar (#4619)

`ids.h` and `ids.cpp` are the manual edits, everything else is
search-and-replace.

The full list of things moved is:

- `TypeId::TypeType`
- `TypeId::AutoType`
- `TypeId::Error`
- `ConstantId::Error`

This is to unblock removing `InstId::Builtin*`.
