feat(v8): Add @sentry/aws-serverless package

[AbhiPrasad]

ref #10976

This change renames the @sentry/serverless SDK to be @sentry/aws-serverless and removes all GCP related code. It also adds a migration note detailing the changes we made.

It also updates the package to only emit CJS, because it relies on monkeypatching via require calls. We can add back ESM at a later point, will create follow up issue for it.

This PR does not touch any of the lambda layer code, I will come back and refactor it afterwards (too scary to think about right now)

Update: We will rename the @sentry/google-cloud package to @sentry/google-cloud-serverless in a follow up PR

Getting same error as I am in #10997

Let me try using require import

Might be a bun bug!

Update: It's not! it's because we needed to use require
