This should allow the cmake build for the opencl runtime to work
without manually adding these definitions. The PAL build also adds
these as private defines in its build, so change rocm to match. This
should probably be including these a config header to benefit other
builds, but this will at least avoid some clutter in the opencl build
for now.
