Roland Shoemaker feb024f415 crypto/x509: use platform verifier on darwin
When VerifyOptions.Roots is nil, default to using the platform X.509
certificate verification APIs on darwin, rather than using the Go
verifier. Since our oldest supported version of macOS is 10.12, we are
able to use the modern verification APIs, and don't need to resort to
the complex chain building trickery employed by chromium et al.

Unfortunately there is not a clean way to programmatically add test
roots to the system trust store that the builders would tolerate. The
most obvious solution, using 'security add-trusted-cert' requires human
interaction for authorization. We could also manually add anchors to
the constructed SecTrustRef, but that would require adding a whole
bunch of plumbing for test functionality, and would mean we weren't
really testing the actual non-test path. The path I've chosen here is
to just utilize existing valid, and purposefully invalid, trusted
chains, from google.com and the badssl.com test suite. This requires
external network access, but most accurately reflects real world
contexts.

This change removes the x509.SystemCertPool() functionality, which will
be ammended in a follow-up change which supports the suggested hybrid
pool approach described in #46287.
