Minimize dependencies of VPN implementations (#1057)
### OpenVPN

- Make CPassepartoutCryptoOpenSSL agnostic of PassepartoutKit
- Move Allocation/ZeroingData from PassepartoutKit to package for
internal use
  - Rename ZeroingData.count to .length for consistency with NSData
  - Duplicate some Data manipulation code in CryptoOpenSSL
- Retain a simplified version of ZeroingData in PassepartoutKit
(AutoerasingData)

### WireGuard

- Make WireGuardKit imports `internal`
