Replace absl::make_unique with std::make_unique

These have been the same for some time. At least one of these
absl::make_unique calls was actually relying on a transitive include
that goes away when absl::optional and absl::variant become
std::optional and std::variant.

Switch to the standard spelling, which is both more consistent and
doesn't rely on a transitive include deep in Abseil.
