[gtk+/composite-templates] Make GtkToolbar honour css border and padding

[Juan Pablo Ugarte <jpu src gnome org>]

commit 22de92df8a0a38b0a26cca1151e4009b6b9e29e6

    Make GtkToolbar honour css border and padding
    
    The widget is already calling gtk_render_frame, but is not measuring css
    border and padding when negotiating its size. This patch replaces the
    already existing get_internal_padding static helper with a function that
    sums the old internal-padding value with the values specified via css.
