Document guarantee that we do not move from rvalue arguments if no insertion happens with absl::raw_hash_map::try_emplace, as done with std::unordered_map::try_emplace.

Make the unit tests for absl::any, absl::optional, and absl::variant
no-ops when these types are just aliases for the corresponding std::
types. We have no way to fix standard library implementation bugs, so
don't bother working around them.
Also disable the corresponding exception-safety tests as well when
exceptions are not enabled.
Fixes https://github.com/abseil/abseil-cpp/pull/360
