Allocate memory for borders and padding members of NGPhysicalBoxFragment if needed

This patch changes memory layout of |NGPhysicalBoxFragment| based on value of
borders and padding as
 - No borders and no padding
  |NGPhysicalBoxFragment|, children[]
 - having both borders no padding
  |NGPhysicalBoxFragment|, children[], borders, padding
 - borders and no padding
  |NGPhysicalBoxFragment|, children[], borders
 - no borders and padding
  |NGPhysicalBoxFragment|, children[], padding
for reducing memory usage, since borders and padding are frequently zero.

(cherry picked from commit 8318aa75176654769ece376cd71fd9fc5deef823)
