feat: do not export def bodies by default (#8221) 
This PR adjusts the experimental module system to not export the bodies
of `def`s unless opted out by the new attribute `@[expose]` on the `def`
or on a surrounding `section`.

convention.

feat: generalize panic to Sort (#6333) 
This PR generalizes the panic functions to a type of `Sort u` rather
than `Type u`. This better supports universe polymorphic types and
avoids confusing errors.

An minimal (but somewhat contrived) example of such a confusing error
is:

```lean
/-
stuck at solving universe constraint
  ?u.59+1 =?= max 1 ?u.7
while trying to unify
  Subtype.{?u.7} P : Sort (max 1 ?u.7)
with
  Subtype.{?u.7} P : Sort (max 1 ?u.7)
-/
def assertSubtype! {P : α → Prop} [Inhabited (Subtype P)] (a : α) [Decidable (P a)] : Subtype P := -- errors on :=
  if h : P a then 
    ⟨a, h⟩ 
  else 
    panic! "Property not satisified"
```

chore: extend GetElem with getElem! and getElem? (#3694) 
This makes changes to the `GetElem` class so that it does not lead to
unnecessary overhead in container like `RBMap`.

The changes are to:
1. Make `getElem?` and `getElem!` part of the `GetElem` class so they
can be overridden in instances.
2. Introduce a `LawfulGetElem` class that contains correctness theorems
for `getElem?` and `getElem!` using the original definitions.
3. Reorganize definitions (e.g, by moving `GetElem` out of
`Init.Prelude`) so that the `GetElem` changes are feasible.
4. Provide `LawfulGetElem` instances to complement all existing
`GetElem` instances in Lean core.

To reduce the size of the PR, this doesn't do the work of providing new
`GetElem` instances for `RBMap`, `HashMap` etc. That will be done in a
separate PR (#3688) that depends on this.
