test(tests/lean/run): define brec_on and binduction_on for a reflexive type
...
We say an inductive type T is reflexive if it contains at least one constructor that
takes as an argument a function returning T.
For reflexive types it doesn't seen to be possible to define a single
brec_on that can eliminate to Type.{>=1} and Prop.
The universe level expressions get too complicated.
Even if we extend the universe constraint solver in the kernel, the
additional complexity might be a problem.
We workaround this issue by defining two versions of brec_on:
- One (brec_on) that eliminates to Type.{>=1}, and
- binduction_on that eliminates to Prop.
For non-reflexive types, we can combine both of them.

fix(frontends/lean/inductive_cmd): inductive datatype elaborator was 'fixing' parameter mismatches.

Given a datatype C with parameters As, if the declaration contained
(C Bs), the elaborator would silently replace it with (C As).
This bug would confuse users and make them believe they define something
different.
