Fix or workaround recent extension API compatibility issues

- Add compatibility methods for `RenderingDevice::shader_create_from_bytecode`
  and `CodeEdit::get_text_for_symbol_loopup`.
- Silence errors which now have compatibility methods.
- Acknowledge GraphEdit/GraphNode compat breakage, intended and WIP.
