feat(shader): add buffer device address support to shader profile

- Add support_buffer_device_address flag to shader Profile

- Add global_memory_tracking_failed flag to shader Info

- Track global memory instruction coverage in optimization pass

- Prepare infrastructure for global memory emulation via BDA
