split github jobs

- Move notifications to a separate job, run only on push.
- Build and test will execute on [pull_request, push].
- Use actions-rs/toolchain@v1 to get the rust toolchain.
- Add matrix hook to allow multiple toolchain versions in the future
  (now set to [stable]).
- Run all the cargo tests, not just test_pageserver
