Added features for QSharedPointer and std::shared_ptr (or derived)

This is a request for the following features to be added to Qt for Python

print(ptr): returns something more understandable and appealing than the "ameopen_headless_direct_py.QSharedPointer_ameopen_API object at 0x0000011A7CEA3780>".

Something like "ameopen_headless_direct_py.QSharedPointer<ameopen.API> object at 0x000001A07D63FCC0", or be configurable in the typesystem to print what we want (with keywords to get each part of the pointer: pointed type (without mangling), pointer type, pointer address, etc.

dir() show the data() function of the shared pointer (at least because useful in some cases) + all the functions of the pointed instance (because it can be a derived type, it is important to show the functions of that derived type and not of the initial type of the shared pointer).

In summary, it should return: list(set(dir(ptr) + dir(ptr.data())))
