Use C++17 fold expressions when casting tuples and argument lists

This commit introduces the use of C++17-style fold expressions when
casting tuples & the argument lists of functions.

This change can improve performance of the resulting bindings: because
fold expressions have short-circuiting semantics, pybind11 e.g. won't
try to cast the second argument of a function if the first one failed.
This is particularly effective when working with functions that have
many overloads with long argument lists.
