feat(library/type_context, library): inout ==> out modifier in type class declarations
...
@kha: I decided to implement this change before I start the
type_context modifications. The change did not affect the corelib and
test suite much. The only annoying problem is that `out` cannot be
used to name locals anymore.

fix(library/tactic/cases_tactic): try to clear input hypothesis when performing dependent elimination
...
The `induction h` tactic tries to clear hypothesis `h` after it is
applied. But, before this commit, `cases h` would only try to clear `h`
when performing non-dependent elimination. This was problematic when
writing tactic scripts for automating proofs.

fix(library/tactic/cases_tactic): use inj_arrow instead no_confusion when index is a nested and/or mutually recursive datatype
...
The `no_confusion` construction is only generated for inductive
datatypes supported in the kernel.
Before this commit, given `h : T`, `cases h` could leak the internal encoding
used by the inductive compiler WHEN a nested and/or mutual inductive
datatype is used to index the inductive datatype `T`.
The new test exposes the problem.
The solution implemented in this commit uses inj_arrow lemmas
generated by the inductive compiler. We only use the lemmas
if the target is a proposition. If it is not, we sign an error.
The reason for this limitation is documented in the source code.
cc @jroesch @dselsam
Jared: the information leakage has been fixed. So, students will not be
confused by the internal encoding used in the inductive compiler.
I added the example I posted on slack as a new test.
Note that, the workaround I used has been removed.

feat(frontends/lean): change structure update notation
...
`{s with ...}` is now `{..., ..s}`, which more clearly expresses that the
result type is not necessarily equal to the type of `s` (in absence of an
expected type and a structure name, we still default to the type of `s`).
Multiple fallback sources can be given: `{..., ..s, ..t}` will fall back to
searching a field in `s`, then in `t`. The last component can also be `..`,
which will replace any missing fields with a placeholder.
The old notation will be removed in the future.
