fix(ext/node): error formatting compatibility

[Tango992]

Towards #29801

Gives better error formating based on Node's implementation, especially on AggregateError instance / nested errors. This in turn allows test/parallel/test-assert-deep-with-error.js to pass.

Given this code:

class CustomError extends Error {
  constructor(message) {
    super(message);
    this.name = "CustomError";
    this.cause = new Error("This is the cause of the CustomError.");
  }
}

const aggregateError = new AggregateError([
  new CustomError("Error message 1."),
  new Error("Error message 2."),
], "Multiple errors.");
console.log(aggregateError);

Deno v2.6.7 outputs:

AggregateError: Multiple errors.
    CustomError: Error message 1.
        at file:///index.js:10:3
    Caused by Error: This is the cause of the CustomError.
        at new CustomError (file:///index.js:5:18)
        at file:///index.js:10:3 {
      name: "CustomError"
    }
    Error: Error message 2.
        at file:///index.js:11:3
    at file:///index.js:9:24

This PR outputs:

AggregateError: Multiple errors.
    at file:///index.js:9:24 {
  [errors]: [
    CustomError: Error message 1.
        at file:///index.js:10:3 {
      cause: Error: This is the cause of the CustomError.
          at new CustomError (file:///index.js:5:18)
          at file:///index.js:10:3
    },
    Error: Error message 2.
        at file:///index.js:11:3
  ]
}
