Maganty Rushyendra a4413710f9 Expose get_char_size() from Font instead of BitmapFont
`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
