Hide Stdlib module name from editor tooling output

[zth]

With the latest changes to the stdlib (#7285) we've now got a few places where the Stdlib prefix "leaks" into the editor tooling. Leaks isn't really a correct way of putting it, since it's perfectly valid, but I'm thinking it'd be a good idea to figure out a way of hiding the Stdlib prefix.

A few examples of how it can look:

(array<'a>, Stdlib_Symbol.t) => 'b

('a, 'a) => Stdlib_Ordering.t

Stdlib_Iterator.t<'a> => array<'a>

"detail": "Stdlib.Date.t",

Stdlib.Promise.t<documentSnapshot<'documentdata>>

I'm thinking it'd be preferable if the above instead showed:

(array<'a>, Symbol.t) => 'b

('a, 'a) => Ordering.t

Iterator.t<'a> => array<'a>

"detail": "Date.t",

Promise.t<documentSnapshot<'documentdata>>

Not sure what the best approach here would be. @cristianoc you have any ideas?

Does it show up in compiler error messages too?

Yes:

 We've found a bug for you!
  tst.res:3:12

  1 │ let d = (d:Date.t) => d
  2 │ 
  3 │ let xx = d(1)

  This has type: int
  But this function argument is expecting:
    Stdlib.Date.t (defined as Stdlib_Date.t)

So that needs to be fixed as well. At least I think so.

Perhaps it can be handled directly by the type printing in the compiler.
