feat(kernel/inductive): relax conditions for an inductive datatype in Prop to be able to eliminate into Type
...
The new relaxed version allows us to define the "accessability"
proposition and have an eliminator into Type.
See justification in the new comments at inductive.cpp

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.

refactor(library/logic): cleanup some of the proofs in cast.lean, remove piext axiom
...
Remark: the main motivation for piext was Lean 0.1 simplifier.
We are using a different approach in Lean 0.2.
The axiom is not needed anymore.
It is also not used in any part of the standard library
