Support more elements during a project Transfer.

### Problem Statement

I transferred a project to a client account because it seemed like it would work with no data loss. In actuality I lost:

* all releases
* all historic transactions
* all charts/graphs

So the releases slowly came back, but I embarrassed myself in front of a client saying we'd lose no data transferring the project between orgs and the actuality was empty dashboards, missing transactional history and more.

### Solution Brainstorm

Support more and more things to [transfer gracefully](https://github.com/getsentry/sentry/blob/1f0d53701dbce37832b79bf64bc8e71a792e67da/src/sentry/models/project.py#L294) between orgs or update [docs](https://docs.sentry.io/product/accounts/membership/#transferring-a-project) to be clear what transfers and what doesn't.
