Implement native macOS methods required by device enrollment, namely methods to Create/Get the device key, Sign challenges with it, and to collect device data (aka serial number). The implementation is rather similar to lib/auth/touchid, but simpler in a few aspects: 1. Device keys don't require user interaction (as in they don't cause a touch ID prompt); and 2. There exists, at most, a single device key at all times. I've added a tiny refactor to reuse Apple public key parsing from touchid, plus some changes so touchid doesn't break in the face of unexpected keys (which the device key didn't cause, per se, but my experiments getting to it did). gravitational/teleport.e#514
