Don't use std::any, std::optional, std::variant, and friends on MacOS versions older than 10.14.

Although Xcode 10 includes those headers and makes the types available to use, according to https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes, on MacOS 10.13 and earlier use of any functions (std::get, for example) results in an error message to upgrade to MacOS 10.14.

This fixes https://github.com/abseil/abseil-cpp/issues/207.  See that issue for more information on the error generated.

raw_hash_set_test is still flaky under gcc 4.8.  Since we now have the probe_test, we don't need the PerfectRatio tests.  Just remove them.

i.e. absl_cc_(library|test)

Internal change

Log to FATAL in throw_delegate.h

ABSL_RAW_LOG(FATAL, ...) is guaranteed to abort.
Previously, the code was logging to ERROR and
calling abort() explicitly, which defeated any
integration with absl::raw_logging_internal::AbortHook().

These changes are limited to Abseil internal APIs.
