### Godot version

4.0.beta10 mono and standard

### System information

Windows 10 64bits

### Issue description

When exporting a project, Godot fails to bundle the required DLLs from the GDExtension to the export folder:

```
editor/export/editor_export_plugin.h:123 - Required virtual method EditorExportPlugin::_get_name must be overridden before calling.
  No suitable library found for GDExtension: res://webrtc/webrtc.gdextension. Possible feature flags for your platform: pc, s3tc, windows, x86_64, template, template_debug
```

### Steps to reproduce

Export for Windows with the existing configuration: WebRTC DLLs won't be copied in the export folder
