`get_char_size()` is a public virtual function defined in the `Font` class. Implementations exist for both `BitmapFont` and `Dynamic Font`. However, it was only exposed to the GDScript API through the Bitmap Font, and not for Dynamic Font. This commit exposes the function through `Font` instead. Fixes #23967
