Add a separate wxControlRenderer::DrawButtonLabel() too.

wxControlRenderer::DrawLabel() was used by both wxStaticText and wxButton but
their labels may need to be drawn differently and wxRenderer does have
different DrawLabel() and DrawButtonLabel() to do it. Now also add a separate
method for the buttons to wxControlRenderer.

See #11220.
