Update code object handling for GSL, PAL and ROCm

- Correct GSL path to report targets using the TargetID syntax.

- Correct GSL path to check compatibility of code objects when
  loading.

- Add concept of an device isa and create a registery used by ROCm,
  PAL and GSL.

- Support XNACK and SRAMECC target features consistently for PAL and ROCm.

- Correct logic for NullDevices and asserts to avoid memory coruption.

- Allow all NullDevices to be created for HIP.

- Numerous other code improvements.
