feat(node): Migrate to domains used through AsyncContextStrategy

[timfish]

This PR:

• Removes all the domain specific code from core
• Replaces all the usages of domain.create().bind/run with runWithAsyncContext
• Removes the domain.active hack from the Next.js init since domains are now not created by runWithAsyncContext until after initNode
• Re-exports runWithAsyncContext from @sentry/node

node sdk index is now side effect free :)

[timfish]

Ah, just noticed I still have some domain usages to remove from serverless!

This makes me so happy :)

Speaking of, @timfish would you mind adding a "sideEffects": false to the node SDK's package.json? That will make it tree shakable by webpack. (Not that important but some serverless folks care about bundle size)

We also need to adjust the test in packages/node/test/manual/webpack-domain/index.js

Should we be re-exporting runWithAsyncContext from @sentry/node to make this possible?

Shouldn't we be exporting this API everywhere? Doesn't have to be right now but at some point I think we should, right?

Yup we'll need to re-export this API, since this is how we are going to tell people to do isolation when they manually instrument.

I might change the name of the args option before we export and document this!

[AbhiPrasad]

Oh realized we didn't do the package.json change here, will open up a PR for that!

And this is why you don't do early morning code review 😭 - it is there, just skipped the file completely!
