Hash :b3859a3c Message :Vulkan: disable glFlush deferral optimization for QualComm GPUs.
It appears this optimization causing Manhattan performance regression on
pixel4 with QualComm GPU. It does have a measurable performance
improvement on S20+ that has ARM GPU. This disables this optimization
for QualComm but still leaves it enabled on other GPUs.
