[LayoutNG] Reduces the size of NGPhysical{Box|Text}Fragment

This patch reduces the size of:
* NGPhysicalBoxFragment by a pointer, by removing |style_|
  from NGPhysicalFragment. This field is used only for line
  box and for ellipsis, and thus it is moved to each
  subclasses.
* NGPhysicalTextFragment by 16 bytes, by moving
  |self_ink_overflow_| and |style_| to RareData. Quick
  investigation shows that |self_ink_overflow_| is different
  from |LocalRect()| in 10-20% of the time (on Linux,
  google.com and a few other sites.)
