  -----------
  Address reviewer feedback: fix getWaitCountMax and reduce code duplication

- Fix getWaitCountMax() to use correct bitmasks based on architecture:
  - Pre-GFX12: Use getVmcntBitMask/getLgkmcntBitMask for LOAD_CNT/DS_CNT
  - GFX12+: Use getLoadcntBitMask/getDscntBitMask for LOAD_CNT/DS_CNT
- Refactor repetitive if-blocks for LOAD_CNT, DS_CNT, EXP_CNT into
  a single loop using getCounterRef helper function
- Fix X_CNT to return proper getXcntBitMask(IV) instead of 0
