Increase region space statistics about allocSize of Heap

ART currently uses a concurrent copying garbage collector, and the
corresponding allocation space uses a region space.
So when obtaining the heap state, we need to also fetch the statistics
of the region space.

Bug: 161244406
Test: Call VMDebug_getHeapSpaceStats interface
