…util-singleton

Remove `Singleton` from `system_util.cc` (google#1523)

As part of our ongoing efforts to remove the dependency on Singleton,
this commit rewrites system_util.cc with absl::NoDestructor rather than
Singleton.

There remain many rooms for improvement in practice, but this would be
the simplest way to remove the dependency on Singleton at the moment.

There should be no functional change for shared-library builds such as
mozc_tip64.dll and libmozc.so, where we have never called
FinalizeSingletons() as it is not generally safe. For other standalone
executables, this change means that objects wrapped by NoDestructor will
no longer be destructed and intentionally leaked at the end of the
program.

Other than that, there should be no observable behavior change.
