Subject: [PATCH] stl/tuple: change uarg##N to internal linkage

8b6a9c2 (std::tuple support (Resolving #103) (#104), 2021-03-11) put
uarg##N in all translation units, which includes
boost/phoenix/stl/tuple.hpp or boost/phoenix/stl.hpp, with external
linkage. Thus, we'll run into below error:

> multiple definition of `boost::phoenix::placeholders::uarg1'

Change it to internal linkage.
