Check that absl::int128 works as a std::chrono::duration::rep.

In particular, validate that ...
  std::chrono::time_point<std::chrono::system_clock,
                          std::chrono::duration<absl::int128,
                                                std::atto>>
is a superset (range and resolution) of absl::Time.

Rewrite GetNominalCPUFrequency to use advapi32 instead of shlwapi

Using shlwapi.dll means that gdi32.dll is loaded which then makes process destruction more expensive, which is unacceptable for some uses. There may be other places that pull in gdi32.dll - this just fixes the one.

Cleanup inconsistent usage of __has_attribute

Eliminate the pointer in absl::Flag, which points to n space where we were storing flag's default value. We also eliminate additional (now unnecessary) allocation for flag's default value.
Instead we'll initialize the flags value directly from the value specified in ABSL_FLAG.
If the default value is updated via the call to SetCommandLineOptionWithMode we are replacing pointer to initialization routine to pointer to new default value.
