When calculating the layout size, the problem occurs.

When calculating the layout size, the problem occurs.
because it is calculated smaller when ReorderBiDiLayout() in RTL language.

For example, if layout.length is calculated as 487 in GetLineLayoutForBox()
but length is calculated as 482 in ReorderBiDiLayout()
(SetResizePolicy is USE_NATURAL_SIZE and Set MULTI_LINE)

sample)
    TextLabel labe21 = TextLabel::New();
    labe21.SetResizePolicy( ResizePolicy::USE_NATURAL_SIZE, Dimension::WIDTH );
    labe21.SetResizePolicy( ResizePolicy::USE_NATURAL_SIZE, Dimension::HEIGHT );
    labe21.SetProperty(Toolkit::DevelTextLabel::Property::BACKGROUND, backgroundMap);
    labe21.SetParentOrigin(ParentOrigin::TOP_LEFT);
    labe21.SetAnchorPoint(AnchorPoint::TOP_LEFT);
    labe21.SetProperty(TextLabel::Property::POINT_SIZE, 34.f);
    labe21.SetPosition( 145.f, 100.f);
    labe21.SetProperty( TextLabel::Property::HORIZONTAL_ALIGNMENT, "END" );
    labe21.SetProperty(Dali::Toolkit::TextLabel::Property::TEXT,  "مرحبا بالعالم Hello world" );
