* Done at line 243: "Add validation of `crate` keyword not appearing in the middle of the symbol path"
* Already happened: "Remove validation of unterminated literals (it is already implemented in `tokenize()`)"
* Happens in `unescape()`: "Add validation of character literal containing only a single char"
* Missing: "raw string literals and raw byte string literals"

4575: Use Chalk's built-in representations for fn items and pointers r=matklad a=flodiebold
The `TypeName::FnDef` was just added; the function pointer variant has existed for a while, I just forgot about it because it's special (because fn pointers can be higher-ranked over lifetimes).
We *could* also make `FnPtr` a separate `Ty` variant instead of a `TypeCtor` variant, which would make the conversion code a bit less special-casey, but it doesn't seem worth doing right now.

Function pointers can be 'higher-ranked' over lifetimes, which is why they're
not an application type in Chalk, but since we don't model lifetimes it doesn't
matter for us yet.
4573: Chalk cleanups r=matklad a=flodiebold
- split off the `Interner` impl and the conversion code into their own modules
- use `TypeCtorId` as `AdtId` directly (instead of raw `InternId`s), and rename the type alias `StructId` -> `AdtId`
- provide missing Chalk debug impls

4570: Use Chalk's built-in impls r=matklad a=flodiebold
This contains two changes:
- Chalk has begun adding built-in representations of primitive types; use these in our type conversion logic. There's one somewhat 'iffy' part here, namely references; we don't keep track of lifetimes, but Chalk does, so it will expect a lifetime parameter on references. If we didn't provide that, it could cause crashes in Chalk code that expects the lifetime, so I rather hackily add an (always the same) lifetime placeholder during conversion. I expect that we'll fully switch to using Chalk's types everywhere before we add lifetime support, so I think this is the best solution for now.
- let Chalk know about well-known traits (from lang items), so it can apply its built-in impls.

(I will start splitting up `chalk.rs` in a separate PR, since it's getting pretty big...)
