aws-lambda-nodejs: introduce NodejsFunctionV2 to support Rolldown as a bundler

[garysassano]

Describe the feature

Rolldown is a Rust-based bundler that aims to provide API compatibility with Rollup and performance parity with esbuild.

On December 25, 2024, Rolldown v1.0.0-beta.1 was officially released, marking a major milestone in its development. With its modern design and growing adoption, Rolldown is poised to become the next standard for bundling and is already set to replace both esbuild and Rollup in Vite.

Use Case

In light of these advancements, adding support for Rolldown in the aws-lambda-nodejs module would provide future-proofing with a next-generation bundler aligned with modern frameworks, as well as improved performance through smaller bundle sizes and faster builds enabled by Rust-based optimizations.

Proposed Solution

Monitor Rolldown's stability as it moves toward a production-ready release. Once stable, implement support for it with a new NodejsFunctionV2 construct.

Per https://rolldown.rs/about, Rolldown can also be directly usable as a standalone bundler. Bundling for NodeJs Lambda function could be refactored to use an interface to specify bundler as a property. It needs to be investigated if Rolldown could support current bundling options (such as excluding files, etc.; refer here).

[garysassano]

The current construct has issues with Docker bundling (see #19230) and other stuff. I think it could be beneficial to take the opportunity to move away from it and start fresh.
