Merge 4577: Fix nested inline box fragmentation

This patch fixes when nested inline boxes are fragmented in a
line due to bidi reordering.

Before this change, the fragmented boxes are appended to the
end of |box_data_list_|. Then when |NGInlineLayoutStateStack::
CreateBoxFragments| creates inline boxes in the ascending
order of |box_data_list_|, it failed to add the fragmented
boxes into their parent inline boxes.

This is critical for out-of-flow positioned objects whose
containing block is an inline box, because they expect to be
propagated through all ancestor inline boxes.

|UpdateBoxDataFragmentRange| is a little tricky by appending
to a vector it is iterating. Changing it to insert to the
correct position makes the function even trickier. This patch
changes it to add fragmented boxes to a separate vector, and
let later process |UpdateFragmentedBoxDataEdges| to merge the
vector to |box_data_list_|.
