Ensure that Invoke can support C++17 in the sense that noexcept is part of the type.

bf796ab71653a80498f9374bc8c5111d065c64ba by Abseil Team <absl-team@google.com>:

Fix typo in static_assert message for copy/move constructible by replacing "by" with "be".

8c7c17c40d03a322f304a2fd73ed34462dbf265a by Andy Soffer <asoffer@google.com>:

Add absl::is_function drop-in replacement for std::is_function. Some standard
libraries incorrectly implement std::is_function in a few corner cases. In
particular, libstdc++ functions marked noexcept.

The trick being used here is that function types decay to pointers. After
excluding cases like is_class, etc, we can distinguish function types by
testing for this decay.

Many thanks to ericwf@ for essentially writing this CL.

CMake support for Abseil Random

This change touches almost build-related files for CMake almost exclusively. The one minor exception is random/internal/salted_seed_seq.h. The default warnings configuration for one of our CI builds requests not having named but unused parameters. The change in this file cleans up that warning.
