I *really* want to move these to a unified bitcode format so we just have a single file. I don't want to repeat the mistakes of the ROCm device libs with complex globals though. For now this is the right solution.

There's a file called `gpu/time_utils.h` that also needs these added. (Bonus points if you confirm that `HSA_AMD_AGENT_INFO_TIMESTAMP_FREQUENCY` is 25 MHz (25000000) on that architecture). Should be able to print it from `libomptarget` somewhere since we query it there.
