feat: backward.isDefEq.respectTransparency (part 1) (#12338)
This PR implements preparatory work for #12179. It implements a new
feature in `isDefEq` to ensure it does not increase the transparency
level to `.default` when checking definitionally equality of implicit
arguments. This transparency level bump was introduced in Lean 3, but it
is not a performance issue and is affecting Mathlib. This PR adds the
new feature, but it is disabled by default.
