feat(google-cloud): Add @sentry/google-cloud package

[AbhiPrasad]

ref #10976

in the first step to our serverless changes, introduce a @sentry/google-cloud package that contains all google cloud functions related functionality.

No migration guide yet, will write that after I merge this in and open a PR for the aws changes.

l: I think this is by now disabled by default, so we don't need to overwrite this anymore.

Great work!

Just realized we never tracked the serverless package in the release registry 😅

Let's make sure we add this package (and the AWS one) to the release registry once we're stable with v8. Before adding it to the registry though, we need to ship a stable v8 version first (pre-releases aren't tracked in the registry).
