Cpp17 support for anyany.hpp (#40)

* C++17 support
* Method now is a typename, not a template typename
* .type_descriptor() now is not default(enabled by aa::type_info)
* new macros: anyany_method/anyany_extern_method/anyany_pseudomethod (see anyany/anyany_macro.hpp for syntax and details)
* allow duplicate methods like any_with<A, A, A, B, B, A, A>
* pseudomethods (values in vtable, invoke returns them instead of call)
* reduce header dependency
* separate header
* materialize for references with 'destroy' and 'copy'
* concepts method/regular_method/pseudomethod
* examples are separate cmake project now
