gralloc: Introduce custom content metadata region

Browse Source 
Introduce a new dynamic memory region to store custom content
metadata that has sizing requirements that exceeds the base
1KB region allocated. This region is dynamic to ensure a layer's
memory requirements are only increased when absolutely needed.
