Properties bound by _set(), _get(), _get_property_list() will lost name,hint,hint_string.

The demo Example Node's properties:

I found that in GDExtension side, the PropertyInfo in _get_property_list() will be append successfully, all infomation are exist.
But in godot core, the StringName which reinterpret_cast from GDNativeStringNamePtr will be a empty string, and String which reinterpret_cast from GDNativeStringPtr usually throw a "read access violation" exception in String's constructor( it is not occur certainly, but almost certainly).

I'm pretty sure this is a bug introduced recently, I have been using _set(), _get(), _get_property_list() in GDExtension for some time.

Hmm, I've just stumbled upon this bug, but no crash on my side. It made it impossible for me to save some custom resources defined in a GDExtension with ResourceSaver.save.

Crash may be an another bug, but I can't spcify what is the reson. Usually happen with String and StringName.

I am wondering if #896 could have cause the issue. Have you updated godot-cpp just before opening this issue ? That would fit the timing. (The PR is from 20 days ago while the issue is 17 days old)

Edit: I definitely think this is it. See this diff: https://github.com/godotengine/godot-cpp/pull/896/files#diff-cb29153262065800fe4d2a03e07fe4cee9252eed9aaef30bf96fb1af265b7797L223-L227

Yes, this issue is happen after pulling #896. But I have not ablility to find out the reason from this diff. I hope someone can repair it.

@Daylily-Zeleen can you test #940 and see if it fix your issue ?
