2636: Chalk update and refactoring r=flodiebold a=flodiebold
This updates the Chalk integration to https://github.com/rust-lang/chalk/pull/311, which will presumably get merged soon, and refactors it some more, most notably introducing our own `TypeFamily` instead of reusing `ChalkIr`. It's still mostly the same as `ChalkIr` though, except for using Salsa `InternId`s directly.

It's not very different, except we can directly use Salsa IDs instead of casting
them. This means we need to refactor the handling of errors to get rid of
UNKNOWN_TRAIT though.

2629: Remove imports from hir r=matklad a=matklad
We only used them to avoid self-confirming completions (`use self::foo`), but that can be handled more locally.
