Chun-wei Fan 8093da7ce6 GResource compiler: Prefix static [con|de]strutors with c_name 
When attempting to test Windows support for building libadwaita, since we are
using multiple GResource files, one would hit linker errors where multiple
definitions of the following symbols have been defined, when
glib-compile-resources was invoked without manual register:

resource_constructor_wrapper
resource_destructor_constructor
_arrayresource_constructor
_arrayresource_destructor

In order to avoid that, just prefix the definitions of resource_constructor
and resource_destructor, like what we do when --manual-register is used, with
what we pass in with --c-name so that we ensure that we do not end up in such
name collisions.
