crypto/rsa,crypto/ecdsa,crypto/ed25519: implement PublicKey.Equal
This makes all modern public keys in the standard library implement a
common interface (below) that can be used by applications for better
type safety and allows for checking that public (and private keys via
Public()) are equivalent.
interface {
Equal(crypto.PublicKey) bool
}
Equality for ECDSA keys is complicated, we take a strict interpretation
that works for all secure applications (the ones not using the
unfortunate non-constant time CurveParams implementation) and fails
closed otherwise.
Tests in separate files to make them x_tests and avoid an import loop
with crypto/x509.
Fixes #21704
