Remove unused search-layer APIs The following have zero call sites repo-wide: SearchManager::id: never read or written (also never initialized, nor was it ever used). Search::Worker::elapsed_time(): never called. PV output uses tm.elapsed_time() (TimeManager) directly. (removed callers on 25361e5) MovePicker::begin()/end(): unused private accessors. (removed callers on 8c2d21f) closes https://github.com/official-stockfish/Stockfish/pull/6909 No functional change
