Since the majority of the Hostcall implementation now sits in the commmon layer, the PAL backend simply just needs to invoke it. One thing that is missing though is HSA signal support. The newly added pal::Signal class is a light emulaion of what HSA signals provide. The current implementation is just enough to get Hostcall working, but it can be expanded in the future if needed to fully emulate HSA signals. The major difference for now between PAL and ROCm hostcall implemenations is that PAL doesn't support blocking signals. This will be enabled in the near future. For now use active wait for PAL.
