Document crypto_ec_key_get_subject_public_key() to use compressed format

Document in src/crypto/crypto.h that compressed point format is expected
in DER produced by crypto_ec_key_get_subject_public_key(). This is the
format needed for both SAE-PK and DPP use cases that are the current
users of this function.
