This adds a build of libhsakmt.a and libhsa-runtime64.so to lib-debug that has debugging turned on. These scripts also copy the source directories and sets the compile flag to map them to allow for source level debugging of both hsa and libomptarget libs.

The sources directories for libomptarget, rocr, and roct are currently copied to $AOMP/share/gdb/python/ompd/src .

To get this to work, some cmake variables need to be enabled with the gerrit review .

Do not merge this aomp PR into aomp-dev branch till amd-staging has merged the above gerrit review.
