What does this PR do?

Closes #16520

This PR adds full support for AWS DeleteObjects operations, with the same Input/Output as @aws-sdk/s3-client

const client = new S3Client();

try {
  const response = await client.deleteObjects(["pictures/file_1.png", "pictures/file_3.png"]);
} catch (err: any) {
  //:(
}

try {
  const response = await client.deleteObjects(["styles/main.css", "js/footer.js", { Key: "slow.js", VersionId: "8" }]);
} catch (err: any) {
  //:(
}

• Documentation or TypeScript types
• Code changes

How did you verify your code works?

• I included a test for the new code, or existing tests cover it
• I ran my tests locally and they pass (bun-debug test test/js/bun/s3/s3-multi-delete.test.ts)
• I ran my tests on AWS and they pass

If Zig files changed:

• I checked the lifetime of memory allocated to verify it's (1) freed and (2) only freed when it should be
• I included a test for the new code, or an existing test covers it
• JSValue used outside outside of the stack is either wrapped in a JSC.Strong or is JSValueProtect'ed
• I wrote TypeScript/JavaScript tests and they pass locally (bun-debug test test/js/bun/s3/s3-multi-delete.test.ts)

If new methods, getters, or setters were added to a publicly exposed class:

• I added TypeScript types for the new methods, getters, or setters

The custom-made XML parser deserves a benchmark; it should be very fast!
