feat: more reliable universe level inference in inductive/structure commands (#12514) 
This PR improves universe level inference for the `inductive` and
`structure` commands to be more reliable and to produce better error
messages. Recall that the main constraint for inductive types is that if
`u` is the universe level for the type and `u > 0`, then each
constructor field's universe level `v` satisfies `v ≤ u`, where a
*constructor field* is an argument that is not one of the type's
*parameters* (recall: the type's parameters are a prefix of the
parameters shared by the type former and all the constructors). Given
this constraint, the `inductive` elaborator attempts to find reasonable
assignments to metavariables that may be present:
- For the universe level `u`, choosing an assignment that makes this
level least is reasonable, provided it is unique.
- For constructor fields, choosing the unique assignment is usually
reasonable.
- For the type's parameters, promoting level metavariables to new
universe level parameters is reasonable.

The order of these steps led to somewhat convoluted error messages; for
example, metavariable->parameter promotion was done early, leading to
errors mentioning `u_1`, `u_2`, etc. instead of metavariables, as well
as extraneous level constraint errors. Furthermore, early parameter
promotion meant it was too late to perform certain kinds of inferences.

Now there is a straightforward order of inference:
1. If the type's universe level could be zero, it checks that the type
is an "obvious `Prop` candidate", which means it's non-recursive, has
one constructor with at least one field, and all the fields are proofs.
If it's a `Prop` candidate, the level is set to zero and we skip to step
4.
2. If the type's simplified universe level is of the form `?u + k`, it
will accumulate level constraints to find a least upper bound solution
for `?u`. To avoid sort polymorphism, it adds `1 ≤ ?u + k`, ensuring the
result stays in `Type _`, or at least `Sort (max 1 _)`. It allows other
metavariables to appear in the assignment for `?u`, provided they appear
in the type former, or for `structure` in the `extends` clause.
3. If the type's simplified universe level is then of the form `r + k`,
where `r` is a parameter, metavariable, or zero, then for every
constructor field it will take the `v ≤ r + k` constraint and extract
`?v ≤ r + k'` constraints. It will also *weakly* extract `1 ≤ ?v`
constraints, using the observation that it's surprising if fields are
automatically inferred to be proofs. Once the constraints are collected,
each metavariable is solved for independently. Heuristically, if there
is a unique non-constant solution we take that, or else a unique
constant solution.
4. Any remaining level metavariables in the type former (or `extends`
clause) become level parameters.
5. Remaining level metavariables in the constructor fields are reported
as errors.
6. Then, the elaborator checks that the level constraints actually hold
and reports an error if they don't.

In 2 and 3, there are procedures to simplify universe levels. You can
write `Sort (max 1 _)` for the resulting type now and it will solve for
`_`.

The "accidentally higher universe" error is now a warning. The
constraint solving is also done in a more careful way, which keeps it
from being reported erroneously. There are still some erroneous reports,
but these ones are hard for the checker to reject. As before, the
warning can be turned off by giving an explicit universe.

Note about `extends` clauses: in testing, there were examples where it
was surprising if the universe polymorphism of parent structures didn't
carry over to the type being defined, even though parent structures are
actually constructor fields.

**Breaking change.** Universe level metavariables present only in
constructor fields are no longer promoted to be universe level
parameters: use explicit universe level parameters. This promotion was
inconsistently done depending on whether the inductive type's universe
level had a metavariable, and also it caused confusion for users, since
these universe levels are not constrained by the type former's
parameters.

**Breaking change.** Now recursive types do not count as "obvious `Prop`
candidates". Use an explicit `Prop` type former annotation on recursive
inductive predicates.

Additional changes:
- level metavariable errors are now localized to constructors, and
`structure` fields have such errors localized to fields
- adds module docs for the index promotion algorithm and the universe
level inference algorithm for inductives
- factors out `Lean.Elab.Term.forEachExprWithExposedLevelMVars` for
printing out the context of an expression with universe level
metavariables
- makes universe level metavariable exposure more effective at exposing
level metavariables (with an exception of `sorry` terms, which are too
noisy to expose)

Supersedes #11513 and #11524.
