openssl: add EC.generate

* ext/openssl/ossl_pkey_ec.c (ec_key_new_from_group): Create a new
  EC_KEY on given EC group. Extracted from ossl_ec_key_initialize().
  (ossl_ec_key_s_generate): Added. Create a new EC instance and
  generate a random private and public key.
  (ossl_ec_key_initialize): Use ec_key_new_from_group().
  (Init_ossl_ec): Define the new method EC.generate. This change is
  for consistency with other PKey types.  [ruby-core:45541] [Bug #6567]

* test/openssl/test_pkey_ec.rb: Test that EC.generate works.
