Makes the data upload heaps growable which should avoid running out of memory. The old approach was that if the runtime did not predict running out of memory early enough, the allocator would crash with a "working buffer not big enough" error. Now, if there is an out-of-memory event, the heap is garbage collected and a new one takes its place transparently. The last commit in the sequence drastically lowers memory allocation sizes to trigger the out-of-memory condition easier in sensitive games and will be tweaked before merge.
Fixes #3343
