drm/xe: Make GUC binaries dump consistent with other binaries in devcoredump

All other(hwsp, hwctx and vmas) binaries follow this format:
[name].length: 0x1000
[name].data: xxxxxxx
[name].error: errno

The error one is just in case by some reason it was not able to
capture the binary.

So this GuC binaries should follow the same patern.

v2:
- renamed GUC binary to LOG
