Ed Page 4e1a565b8a refactor: Split out clap_builder for faster derive builds 
For now, we are still treating `clap` as the user facing API for both
builder and derive, making this an internal change as we don't expect
this to negatively impact builder build times all that much.  We can
re-evaluate at a later time and consider having distinct top-level
crates for builder and derive.

Looking at `--timings` on my machine
- `clap` only took 0.04s to build and it happened in
  parallel to `clap_builder` codegen
- this saved 1.7s for derive build times, with `clap_builder` building
  in parallel to `syn` and `clap_builder` and `clap_derive` finishing
  around the same time.

This was discussed some at https://rust-lang.zulipchat.com/#narrow/stream/220302-wg-cli/topic/clap.20build.20times.20and.20.60clap_derive.60.3A.20a.20crazy.20idea
