Create `@sentry/profiling-node` Lambda Layer

As highlighted [here](https://github.com/getsentry/sentry-javascript/tree/master/packages/profiling-node#bundling), there are a few steps needed to successfully make use of `@sentry/profiling-node` in serverless environments.

While there are clear benefits to users bundling all of their code on those environments, it's a complicated process. People often use tools that abstract away low level interactions with bundlers, like [AWS SAM](https://aws.amazon.com/serverless/sam/), which makes it even harder to follow the outlined steps.

We can alleviate that by publishing an AWS Lambda layer for `@sentry/profiling-node` that people can add to their Lambda functions to use `@sentry/profling-node` out of the box.
