Instead of including a `Secp256k1` context per `PeerChannelEncryptor`, which is relatively expensive memory-wise and nontrivial CPU-wise to construct, we should keep one for all peers and simply reuse it. This is relatively trivial so we do so in this commit. Since its trivial to do so, we also take this opportunity to randomize the new PeerManager context.

I was running some heap profiling on an LDK application and noticed we currently allocate a full secp context per peer, so figured I'd just remove it.
