2e338152a2 avformat/mov: use an array of pointers for heif_item 
Pointers to specific entries in the array are stored in other structs, so
in the scenario where heif_item was reallocated when parsing an iloc box after
and iinf one, the pointers may end up referencing freed memory.

Fixes use-after-free with such samples.
