Update SPAKE2p pairing code to match spec

[pan-apple]

Problem

The current pairing code is based on the earlier version of the spec, and the spec has evolved since then. The code needs updates to match the latest specifications.

Summary of Changes

• update message handshake to include PBKDF param exchange
• update msg types and error codes
• add error handling via error message handshake

Fixes #4135
