Moved from RadeonOpenCompute to ROCm

[causten]

AMD recently moved a number of github repos from RadeonOpenCompute to ROCm. Not all, just the ones directly involved with the ROCm stack. Other helper repos may move over time, but for now we need a scan of our source and the places where RadeonOpenCompute is no longer accurate. As an example the README.md references to RadeonOpenCompute should be renamed to ROCm
