feat: Serverless Nag Pack

[Kevinwochan]

Description

https://awslabs.github.io/serverless-rules/

The serverless rules are opinionated best practices compiled by AWS field teams specifically for serverless services
Rules like ensuring the native X-ray tracing is enabled, Lambda loggingConfig is specified, SQS has a re-drive policy
These don't follow any of the compliance requirements in current CDK nag packs and the rules are not already there in CDK nag

Use Case

This provides CDK users best practice checks that are not aligned to compliance requirements

Proposed Solution

1. Review relevance of existing rules
2. Begin adding new rules to cdk-nag
3. Launch the Serverless Nag Pack
