Modularize: Remove pieces that are going in different repos (#876)

This change is part of the modularization and moving things to different repos.

Remove deprecated/private API from `src/index.ts`

Also remove:
- `website/` (moving to another repo)
- `docs/` (moving to another repo)
- `starter/` (moving to another repo)
- `src/data/` (deprecated)
- `demos/`
  - `adder/`
  - `imagenet/`
  - `lstm/`
  - `mnist/`
  - `mnist_eager/`
  - `one_plus_one/`
  - `rune_recognition/`
