Mostly remove pre-CXX11 workarounds.

С++03 support was deprecated in 1.85 and now can be removed. This PR clears
many of workarounds, which are no longer needed now.

* Remove unused workaround macros (many of).
* Remove BOOST_STATIC_ASSERT usages.
* Minimize Boost::type_traits dependency (in favour of STL's type_traits).

Closes https://github.com/boostorg/iterator/pull/82.
