[ruby/openssl] pkey: add PKey#inspect and #oid
Implement OpenSSL::PKey::PKey#oid as a wrapper around EVP_PKEY_id(). This allows user code to check the type of a PKey object. EVP_PKEY can have a pkey type for which we do not provide a dedicated subclass. In other words, an EVP_PKEY that is not any of {RSA,DSA,DH,EC} can exist. It is currently not possible to distinguish such a pkey. Also, implement PKey#inspect to include the key type for convenience. https://github.com/ruby/openssl/commit/dafbb1b3e6
