drm/xe/guc: Handle GuC local uncorrectable error notifications

Browse source

Add support for the GuC uncorrectable local error G2H notification and
opt in to the feature when the submission ABI exposes it.

When the notification targets a known exec queue, treat it like an
engine reset request and route it through the existing timeout cleanup
path. This keeps the queue teardown, pending job cancellation and error
capture in one place instead of open-coding a parallel recovery flow.
