Basic setup for fun_prop for Differentiable(At/On/Within) and HasFDeriv(At/Within/Strict).

Mainly consists of marking theorems with fun_prop attribute but I had to formulate appropriate _pi and _apply theorems. Proofs of _apply theorems can probably be golfed into neater form.

We remove all but one open Classicals, instead preferring to use open scoped Classical. The only real side-effect this led to is moving a couple declarations to use Exists.choose instead of Classical.choose.

The first few commits are explicitly labelled regex replaces for ease of review.

This uses the improved shake script from #9772 to reduce imports across mathlib. The corresponding noshake.json file has been added to #9772.

This has nice performance benefits.
