Document EVP_PKEY_get0_asn1(3), it is declared in <openssl/evp.h>.

It makes no sense to have method enumerators public, but the function
to retrieve the method of a specific public key undocumented.
Besides, it is confusing to have EVP_PKEY_asn1_get0(3) documented
without mentioning the very different EVP_PKEY_get0_asn1(3).
Remove a duplicate .Xr while here,
and reference the related accessor EVP_PKEY_base_id(3).
Triggered by tb@ adding a const qualifier to the argument.
