layout: Add BoxFragment rare data (#38325)

Introduce `BoxFragmentRareData`, rare data for `BoxFragment`, which
would store the specific data that is relevant to several fragments.
This would reduce the `BoxFragment` size to 256 from 264 and add 8 bytes
for fragment that have rare data (due to the additional pointer to the
rare data).

Testing: Existing WPT coverage
