### Tested versions

4.2.0-stable
4.2.1-stable

### System information

Windows 10

### Issue description

Godot release builds (aka export templates) do not provide the `ResourceImporterOggVorbis` methods `load_from_buffer()` and `load_from_file()`. There might be more (now or in the future).

In godot-rust, we noticed it because we check for method availability at startup time. Downstream issue: https://github.com/godot-rust/gdext/issues/489.
**However, this affects all bindings**, including godot-cpp. If someone tries to call the methods, it will fail for exported games. What makes this delicate is that it works in Debug mode but breaks in Release, so it can go undetected.

I think it's OK that not all methods are available, but this information should be exposed via `extension_api.json`, so that bindings can take appropriate steps, e.g. to remove the methods or warn upon their usage.

### Steps to reproduce

In a GDExtension binding, try to call either of the following methods:
- `ResourceImporterOggVorbis::load_from_buffer` 
- `ResourceImporterOggVorbis::load_from_file`
