Remove duplicate identical make*MemoryBarrier

Remove duplicate identical make*MemoryBarrier

This change adds a new util, vkBarrierUtil, which contains barrier
creation functions. The framework had 8 identical copies of these
functions. Apart from the identical ones, couple other barrier
making functions were also moved into the new util to have them
in the same place. The two makeImageBarrier functions were merged
using default parameters.

The affects-list is overly broad, but not easily measurable since the
changes may affect tests outside the directly edited files.

Affects:

dEQP-VK.*

Components: Vulkan, Framework

VK-GL-CTS issue: 1472
