`performance.nodeTiming.uvMetricsInfo` returns the libuv event loop metrics as numbers, which are only exact up to `Number.MAX_SAFE_INTEGER`. Add `uvMetricsInfoBigInt`, which returns the same metrics as bigints backed by `uint64_t` storage, carrying the full 64-bit range reported by libuv. A single native call fills both a `Float64Array` and a `BigUint64Array`, so `uvMetricsInfo` does not pay for bigint allocation and conversion. The new property is omitted from `toJSON()`, as `JSON.stringify()` cannot serialize bigints.
