Martti MalmiandDev cd56fee7cf identity: eagerly precompute pubkey_full in PeerIdentity::from_pubkey
`PeerIdentity::pubkey_full()` falls through to
`self.pubkey.public_key(Parity::Even)` whenever the parity-aware full
key wasn't passed at construction (i.e. for every peer constructed
from an npub or x-only key). Underneath, that runs a secp256k1 EC
point parse — `fe_sqrt` + `fe_mul` + `ge_set_xo_var` — which is ~6%
of per-packet CPU on the bulk-data send path for a value that never
changes after construction.

Compute it eagerly. The same EC point parse already runs at
construction inside `NodeAddr::from_pubkey`, so the cost is paid once
where it would be paid anyway.
