    [corlib]: Cleanup `X509Certificate` implementation and sync it with CoreFX.

    Completely refactored the `X509Certificate` implementation to make it based very closely on CoreFX.

    We cannot fully switch to their implementation yet because we are missing things and they also have
    a few issues in their implementation.  However, this will make it a lot easier to do this at a later time.

    The internal `X509CertificateImpl` has been cleaned up as well, using properties instead of methods in
    most places and the `ToString()` implementation is now shared between all platforms.

    * `X509Certificate.GetSerialNumberString()`: we keep the our old behavior here as their change seems to
      be a regression - see https://github.com/dotnet/corefx/issues/30543.

    * `X509Certificate.CreateFromSignedFile()`: in CoreFX, this is the same as `CreateFromCertFile()`.
      Our old implementation was incomplete and did not verify the signature - we even had a test where
      loading a certificate with an invalid signature was supposed to work; this test has been disabled
      because we're now throwing an exception.

    * `X509CertificateImpl.KeyAlgorithmParameters`: this is supposed to throw `CryptographicException`
      on error, see `Certificate13` in `X509CertificateTest.cs`.

    * We now match CoreFX's behavior regarding serialization - while the `X509Certificate` type is still
      marked as `[Serializable]`, we now throw `PlatformNotSupportedException` when attempting to serialize
      or deserialize it.

    [MacOS] On Mac, use the copyfile API to copy files

    Rebase of #9038 with added fix for the failing unit tests. Note that there's a race condition in the check between `source file == destination file` and the `copyfile` call, but a similar race condition already exists there in the current code except the outcome is different.

    Use `SafePasswordHandle` in the internal certificate APIs. (#9651)

    * `X509Helper`, `X509CertificateImpl`, `X509Certificate2Impl` and `ISystemCertificateProvider` now use `SafePasswordHandle` instead of strings.

    * `X509Certificate`: actually implement `SecurePassword` based APIs using `SafePasswordHandle`.

    * `mono_btls_pkcs12_import()`: when passed an empty password, try both the empty string and null.
