[cogl] Remove the cogl_foo_init_from_foo copy constructors

    Remove the cogl_foo_init_from_foo copy constructors
    
    The CoglQuaternion type is allocated by the caller and can not have
    any additional resources so it should be obvious that you can just use
    the regular assignment operator to copy them. None of the other types
    except the commented out vec4 type have a copy constructor so we
    might as well remove these too.
