Merge #447

447: Add implementation for critical-section 1.0 r=adamgreig a=Dirbaio

Picking up #433 since it seems stalled. Changes from #433 are:
- Update to `critical-section 1.0.0-alpha.2`
- Use `bool` restore token
- Name Cargo feature `critical-section-single-core`.

TODO before merging:

- [x] Wait for `critical-section 1.0` release https://github.com/rust-embedded/critical-section/pull/19
