refactor: Introduce PProdN module (#4807 )

code to create nested `PProd`s, and project out, and related functions
were scattered in variuos places. This unifies them in
`Lean.Meta.PProdN`.

It also consistently avoids the terminal `True` or `PUnit`, for slightly
easier to read constructions.

feat: .below and .brecOn for nested inductive (#4658 )

We now get `.below` and `.brecOn` definitions for nested inductives.

No surprises in the implementation: the kernel already gives us suitable
`.rec_1` etc. recursors, and our construction follows the structure of
this recursor.
