98ee789990 refactor: InductiveVal.numNested instead of .isNested 
right now, in order to find out how many auxilary datatype are in a
mutual group of inductive with nested data type, one has to jump
through hoops like this:

```
private def numNestedInducts (indName : Name) : MetaM Nat := do
  let .inductInfo indVal ← getConstInfo indName | panic! "{indName} is an inductive"
  let .recInfo recVal ← getConstInfo (mkRecName indName) | panic! "{indName} has a recursor"
  return recVal.numMotives - indVal.all.lengt
```

The `InductiveVal` data structure already has `.isNested : Bool`, so it
seems to be a natural extension to beef that up to `.numNested: Nat`.

This touched kernel code.

feat: collect kernel diagnostic information (#4082) 
We now also track which declarations have been unfolded by the kernel
when using
```lean
set_option diagnostics true
```

06e057758e chore: Remove unused variables from kernel 
when I build lean locally, I get a nice and warning-free build
experience with the exception of these two unused variables. They can
probably go?

0d5ac5288a feat(runtime): increase small nat size 
In 64-bit machines, the max small nat value should now be (2^63 - 1), and on 32-bit
machines (2^32 - 1).

The main motivation for this modification are the array indexing
operations. With the new representation, if a Nat index is not small,
then it must not be a valid index. This was not true in 64-bit
machines. Example: an array of size 2^33 would fit in memory, and but
an index `i` > 2^32 - 1 would not be a small nat value.
