Ensure that ECX keys pass EVP_PKEY_param_check()
RSA keys have no parameters and pass EVP_PKEY_param_check(). Previously,
ECX keys had no parammeters and failed EVP_PKEY_param_check(). We should
be consistent. It makes more sense to always pass, and therefore this
commit implements that behaviour.
Fixes #14482
