rocr: GPU core file location support (#1732)

* rocr: WIP Support dump of GPU core file

* WIP new core dump tests compile

* WIP: anony namespaces, test updates, progress

Added disabled Fault test. Other non-disabled coredump tests don't work.

* WIP: address code review feedback

* WIP: gpu core dump rocrtst works; combined

* WIP: remove rocrtst changes for this commit
