aws-cdk: Replace __dirname

[cyntheticfox]

Describe the feature

Replace the global variable __dirname used with an alternative that properly handles special characters and is more widely supported

Use Case

I've seen issues in #21161, and #18470, and may be running into issues myself due to path resolution shenanigans on my system with the __dirname global variable.

Proposed Solution

It seems feasible from my limited knowledge of Node.js to use path.dirname(url.fileURLToPath(import.meta.url)) instead, given its introduction back in Node.js 10.12.

Other Information
