[perf] Remove unused perf-upload-worker

perf/go/perfresults/workflows/worker never registers any Temporal
workflows or activities, so the perf-upload-worker WorkerDeployment in
skia-infra-public-dev was stuck in WaitingForPollers / NotRegistered
since 2026-07-06 and fired RunningK8sAppNotCheckedIn. The
WorkerDeployment was deleted from skia-infra-public-dev and never existed
in skia-infra-public or skia-infra-corp.

Remove the binary and its perf_upload_worker image target. Nothing else
depends on this package.
