feat(layers): introduce new CDK Python constructor for Powertools Lambda Layer

[leandrodamascena]

Issue number: #5278

Summary

Changes

This PR introduces a new CDK Python constructor for creating Lambda Layers, replacing the previously used powertools-lambda-layer-cdk project. This change aims to simplify our project structure, improve control over dependencies, and enhance our release process efficiency.

We've decided to move away from the powertools-lambda-layer-cdk project due to some issues:

1. Projen usage: The powertools-lambda-layer-cdk uses projen, which has caused issues in the past, particularly with its obscure management of transitive dependencies.
2. Lack of documentation: The powertools-lambda-layer-cdk project is poorly documented, leading to uncertainties in our automation processes.
3. Unnecessary complexity: Using an external CDK constructor for a layer we have full control over adds unnecessary complexity to our project.
4. Release process slowdown: The external constructor has been slowing down our release process by approximately 10 minutes.

Changes

• Removed dependency on powertools-lambda-layer-cdk
• Introduced a new custom CDK Python constructor for creating Lambda Layers
• Adjusted CI/CD pipelines to utilize the new constructor
• Added a new quality check step for this constructor
