[gtksourceview] Enable wrapping for the default info widget

    Enable wrapping for the default info widget
    
    The solution is to set a -1, -1 size request before setting text in the label.
    Then after setting the proposal info text in the label, check the size request
    and if it exceeds the maximum width, explicitly force the width to that
    specific size.
