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

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.
