Tracks the registers that explicit and hidden arguments are preloaded to with new code object metadata. IR arguments may be split across multiple parts by isel, and SGPR tuple alignment means that an argument may be spread across multiple registers. To support this, some of the utilities for hidden kernel arguments are moved to `AMDGPUArgumentUsageInfo.h`. Additional bookkeeping is also needed for tracking purposes.
