8942: Add `library` semantic token modifier to items from other crates r=arzg a=arzg
Closes#5772.
A lot of code here is pretty repetitive; please let me know if you have any ideas how to improve it, or whether it’s fine as-is.
Side-note: How can I add tests for this? I don’t see a way for the test Rust code in `test_highlighting` to reference other crates to observe the new behaviour.

The problem was the skipping of binders in
`resolve_method_call_as_callable`; this still doesn't use the _correct_
substitution, but at least it doesn't return a type with free variables
in it.
Fixes#8931.
We can't do the easy hack that we did before anymore, where we kept
track of whether any inference variables changed since the last time we
rechecked obligations. Instead, we store the obligations in
canonicalized form; that way we can easily check the inference variables
to see whether they have changed since the goal was canonicalized.
8813: Get some more array lengths! r=lf- a=lf-
This is built on #8799 and thus contains its changes. I'll rebase it onto master when that one gets merged. It adds support for r-a understanding the length of:
* `let a: [u8; 2] = ...`
* `let a = b"aaa"`
* `let a = [0u8; 4]`
I have added support for getting the values of byte strings, which was not previously there. I am least confident in the correctness of this part and it probably needs some more tests, as we currently have only one test that exercised that part (!).
Fixes#2922.

Fix#2922: add unknown length as a condition for a type having unknown.
Incorporate reviews:
* Extract some of the const evaluation workings into functions
* Add fixmes on the hacks
* Add tests for impls on specific array lengths (these work!!! 😁)
* Add tests for const generics (indeed we don't support it yet)
8745: Support goto_type_definition for types r=matklad a=Veykril
I'm unsure if the approach of lowering an `ast::Type` to a `hir::Type` is a good idea, it seems fine to me at least.
Fixes#2882

Store impls for e.g. &Foo with the ones for Foo instead of the big
"other" bucket. This can improve performance and simplifies the HIR impl
search a bit.
Almost all uses actually only care about ADT substs, so it's better to
be explicit. The methods were a bad abstraction anyway since they
already didn't include the inner types of e.g. `TyKind::Ref` anymore.
