[PATCH v2 3/7] drm/xe/guc: Print register addresses in capture snapshot output

[Nareshkumar Gollakoti <naresh.kumar.g@intel.com>]

Include register offsets in GuC capture snapshot print output for both
32-bit and 64-bit registers.

When dumping captured engine register state, print each register name
alongside its MMIO offset to make the snapshot output easier to
cross-reference with register definitions and hardware debug
documentation.

This improves postmortem analysis without changing capture contents.

v2:(Sashiko)
- Ensure lower DWORD prints
