9331945e8b fix(library/init/meta/interactive): alternative fix for issue at #1913 
We also document the problem to make sure we don't spend time again
trying to understand the workaround. This is an instance of a bigger
problem that should be addressed later.

77ae133baa fix(library/type_context): preprocess_class 
@kha This commit fixes the bug we discussed on slack.
I had to repair one of the tests. The broken test made me
realize that if we use the unbundled approach to define something like
`is_semiring`

```
class is_semiring (α : Type) (plus : α → α → α) (mul : α → α → α) (zero : out_param α) (one : out_param α) :=
...
```
Then, to retrieve a `is_semiring` instance, we need to know `α`, `plus`
and `mul`. This is problematic because we may be in a context where one
of them cannot be inferred. This would force user to manually provide
the missing (input) parameter. We are not considering the unbundled
approach for complex algebraic structures such as `semiring`, `ring` and
`field`, but I wanted to document this limitation here since we may face
it in other type classes.

I think it is a bad idea to add back `inout_param` and have both:
`inout_param` and `out_param`. The previous `inout_param` created
many instabilities and hard to diagnose failures.

c195d7c2a1 feat(library/tactic/simp_tactic): improve mk_simp_attr 
- An new simp attribute may depend on other existing attributes

- Add `[norm]` simp attribute. It is an extension of the default `[simp]` attribute.
  It should be used to add extra rules for normalizing goals.
  These extra rules are used to produce normal forms and/or reduce the
  number of constants used in a goal. Here is an example coming from a
  discussion with @kha. When working with monads, we may want to
  eliminate `<$>` by using the lemma `f <$> x = x >>= pure ∘ f`.
  This lemma is in the `[norm]` simp set, but it is not in `[simp]`
