Merge #5347 
5347: Chalk writer integration r=flodiebold a=detrumi

~~This adds a `rust-analyzer dump-chalk` command, similar to analysis-stats, which writes out the whole chalk progam (see [chalk#365](https://github.com/rust-lang/chalk/issues/365) for more info about the .chalk writer)~~

Write out chalk programs in debug output if chalk debugging is active (using `CHALK_DEBUG`).

Example output:
```
[DEBUG ra_hir_ty::traits] solve(UCanonical { canonical: Canonical { value: InEnvironment { environment: Env([]), goal: Implemented(SeparatorTraitRef(?)) }, binders: [] }, universes: 1 }) => None
[INFO  ra_hir_ty::traits] trait_solve_query(Implements(fn min<?0.0>(?0.0, ?0.0) -> ?0.0: Deref))
[DEBUG ra_hir_ty::traits] solve goal: UCanonical { canonical: Canonical { value: InEnvironment { environment: Env([]), goal: Implemented(SeparatorTraitRef(?)) }, binders: [U0 with kind type] }, universes: 1 }

    where

    trait Deref {
      type Assoc_1829: Sized;
    }
