feat(middleware-flexible-checksums): use Node.js native CRC32 checksum API

[trivikr]

Issue

• Internal JS-5553
• zlib: expose zlib.crc32() nodejs/node#52692
• chore: add Node.js CRC32 for comparison trivikr/benchmark-aws-crt-crc32#2

Description

Uses Node.js native CRC32 checksum API, when available

Testing

import assert from "assert";
import { S3 } from "../aws-sdk-js-v3/clients/client-s3/dist-cjs/index.js";

const s3 = new S3({ region: "us-west-2" });
const Bucket = "test-flexible-checksums"; // Change to your bucket name
const Key = "test.txt";
const Body = "helloworld".repeat(10_000_000); // A string of size ~100MB

const putObjectStart = performance.now();
await s3.putObject({ Bucket, Key, Body, ChecksumAlgorithm: "CRC32" });
console.log("time taken for putObject request:", (performance.now() - putObjectStart).toFixed(2), "ms");

const getObjectStart = performance.now();
const response = await s3.getObject({ Bucket, Key, ChecksumMode: "ENABLED" });
console.log("time taken for getObject request:", (performance.now() - getObjectStart).toFixed(2), "ms");

const transformStart = performance.now();
const body = await response.Body.transformToString();
console.log("time taken for transform (checksum validation):", (performance.now() - transformStart).toFixed(2), "ms");

assert(body === Body);

Without Node.js native CRC32 (node v20.10.0)

time taken for putObject request: 3399.14 ms
time taken for getObject request: 1145.27 ms
time taken for transform (checksum validation): 2137.78 ms

With Node.js native CRC32 (node v20.17.0)

time taken for putObject request: 1427.59 ms
time taken for getObject request: 1141.85 ms
time taken for transform (checksum validation): 246.76 ms
