uhd: Replace all occurrences of boost::bind with std::bind

Note: Replacing everything with a lambda would be even better, but that
can't be easily scripted so we'll do this as a first step to reduce the
Boost footprint.

This also removes occurences of #include <boost/bind.hpp>, and makes
sure all usages of std::bind have an #include <functional>. clang-format
wasn't always applied to minimize the changeset in this commit, however,
it was applied to the blocks of #includes.

Due to conflicts with other Boost libraries, the placeholders _1, _2,
etc. could not be directly used, but had to be explicitly called out
(as std::placeholders::_1, etc.). This makes the use of std::bind even
uglier, which serves as another reminder that using std::bind (and even
more so, boost::bind) should be avoided.

nirio/rpc/rpc_client.cpp still contains a reference to boost::bind. It
was not possible to remove it by simply doing a search and replace, so
it will be removed in a separate commit.
