Bug 1460439 - Conversion from NS_STYLE_BORDER_STYLE_* macro to StyleBorderStyle::* enum class r=emilio Converted NS_STYLE_BORDER_STYLE_* consts to enum class. Updated corresponding values to enum class. reduced BCCornerInfo struct values to fit StyleBorderStyle values inside struct. Added defaults to switches that do not fully cover all instances of StyleBorderStyle.
