Switch remaining uses of ant over to sbt

- Modify `tools/scaladoc-diff` to use sbt instead of ant.

- Move `stability-test.sh` from `tools` to `scripts`. With the new
  build process without separate `locker` and `strap` stages, it doesn’t
  make sense to call this script without first setting up the proper
  test environment in a CI build.

- Replace the use of `build.number` in `bootstrap` with a new
  `SHA-NIGHTLY` mode for `baseVersionSuffix`.

- Make `partest` call sbt instead of ant for initializing the classpath
  and use the new classpath location (`quick` instead of `pack`).
