This function is duplicated across clCopyImages files, so just keep one
definition in common file, and get rid of the duplicated ones.

* set gDeviceType in testharness.c, also moved gTestRounding to imageHelpers.cpp & .h and removed duplicate code from host_atomics.cpp
* Cleaned up some redundant code
* Reversed the change in testharness.c
Some of the setup functionality is already there in the test harness, so
use that and remove the duplicated code from within the suite.
