Reverts #49505
Initiated by: jonahwilliams
This change reverts the following previous change:
Original Description:
part of flutter/flutter#140804
We can't use the existing host buffer abstraction as that requires us to collect all allocations up front. By itself, this isn't sufficient for #140804 , because we'll need a way to mark ranges as dirty and/or flush if we don't have host coherent memory. But by itself this change should be beneficial as we'll create fewer device buffers and should do less allocation in general.
The size of the device buffers is 1024 Kb, somewhat arbitrarily chosen.
