Cleanup dependencies

[havogt]

Resolve dependencies to GridTools as follows.

• Removed from GridTools: any_moveable.hpp, copy_into_variadic.hpp, is_there_in_sequence_if.hpp
• integer_sequence moved into make_indices.hpp (GT with c++14 doesn't have it integer_sequence anymore; the rest is trivial.)
• Duplicated and moved to cpp_bindgen namespace: type_traits.hpp (removed unused aliases, probably duplications are removed from GT with c++14), for_each.hpp (removed device variants).

Additional changes:

• New namespace cpp_bindgen replaces gridtools::c_bindings
