Verifies a raw P-256 signature over a Soroban authorization payload hash.
key_data must be a 65-byte uncompressed SEC1 point (0x04 || X || Y),
and sig_data must be a low-S 64-byte compact signature (r || s). The
supplied 32-byte hash is passed directly to the Soroban host without
another hashing step.

with the uncompressed SEC1 prefix 0x04.Error(Crypto, InvalidInput) - the point, signature
