Subject: [PATCH 1/3] Use OpenSSL::PKey::EC.generate to generate ECC key pairs
When Ruby/OpenSSL is built against OpenSSL 3.0, OpenSSL::PKey::PKey
instances are immutable and OpenSSL::PKey::EC#generate_key cannot work
because it modifies the receiver.
OpenSSL::PKey::EC.generate is available on Ruby 2.4 (Ruby/OpenSSL 2.0)
or later.

Subject: [PATCH 2/3] Use OpenSSL::X509::Certificate#check_private_key
The method is for the exact purpose: to check that an instance of
OpenSSL::PKey::PKey matches the public key in a certificate.

Subject: [PATCH 3/3] Fix Gem::Security.get_public_key on OpenSSL 3.0
Ruby/OpenSSL 2.2 added OpenSSL::PKey::PKey#public_to_der for serializing
only the public key components contained in the instance. This works
for all possible key types.
