7892: Fix TokenStream::from_str for input consisting of a single group with delimiter r=edwin0cheng a=kevinmehall
TokenStream holds a `tt::Subtree` but assumes its `delimiter` is always `None`. In particular, the iterator implementation iterates over the inner `token_trees` and ignores the `delimiter`.
However, `TokenStream::from_str` violated this assumption when the input consists of a single group by producing a Subtree with an outer delimiter, which was ignored as seen by a procedural macro.
`tt::Subtree` is just `pub delimiter: Option<Delimiter>, pub token_trees: Vec<TokenTree>`, so a Subtree that is statically guaranteed not to have a delimiter is just `Vec<TokenTree>`.

Currently it replaces escape sequence with the actual value, which is very wrong for `"\n"`.

7894: generate_function assist: convert arg names to lower snake case r=Veykril a=JoshMcguigan
This PR fixes one of the points listed by @TimoFreiberg in #3639. Specifically that all generated argument names should be converted to lower snake case.
```rust
struct BazBaz;
fn foo() {
bar$0(BazBaz);
// ^ when triggering the assist here, you get the output below
}
// BEFORE
fn bar(BazBaz: BazBaz) ${0:-> ()} {
todo!()
}
// AFTER
fn bar(baz_baz: BazBaz) ${0:-> ()} {
todo!()
}
```

`TokenStream` assumes that its subtree's delimeter is `None`, and this
should be encoded in the type system instead of having a delimiter field
that is mostly ignored.
`tt::Subtree` is just `pub delimiter: Option<Delimiter>, pub
token_trees: Vec<TokenTree>`, so a Subtree that is statically guaranteed
not to have a delimiter is just Vec<TokenTree>.
TokenStream holds a `tt::Subtree` but assumes its `delimiter` is always
`None`. In particular, the iterator implementation iterates over the
inner `token_trees` and ignores the `delimiter`.
However, `TokenStream::from_str` violated this assumption when the input
consists of a single Group by producing a Subtree with an outer
delimiter, which was ignored as seen by a procedural macro.
In this case, wrap an extra level of Subtree around it.

7870: Use chalk_ir::AdtId r=Veykril a=Veykril
It's a bit unfortunate that we got two AdtId's now(technically 3 with the alias in the chalk module but that one won't allow pattern matching), one from hir_def and one from chalk_ir(hir_ty). But the hir_ty/chalk one doesn't leave hir so it shouldn't be that bad I suppose. Though if I see this right this will happen for almost all IDs.
I imagine most of the intermediate changes to using chalk ids will turn out not too nice until the refactor is over.
