Create `@sentry/profiling-node` Lambda Layer

[andreiborza]

As highlighted here, 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, 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.

Would really like to see this. Am having issues with esbuild not copying over .node files even with '.node': 'copy', and this would solve that.
