We still fallback to environment.deployment_platform until we can
backfill

All deployments should have already their cluster_id filled in on
creation. Legacy deployments will not be retried as:-

* Ci::Build#retry calls `Ci::RetryBuildService`
* Ci::Pipeline#retry
calls `Ci::RetryPipelineService` which also calls
`Ci::RetryBuildService`
* `Ci::RetryBuildService` will clone a build to retry

It is also impossibly to backfill Deployment#cluster_id from
Project#deployment_platform correctly as clusters could have been
deleted, added or altered in the intervening time.

A deployment will have a cluster associated on creation if there is one.

Otherwise fallback to deployment_platform for legacy deployments.

We nullify when cluster is deleted as we want to keep the deployment
record around.

Add cluster as an optional association

We will have only cluster for deployments where the build deploys to a
kubernetes cluster

Fix failing spec/models/internal_id_spec.rb spec

Closes #63698

See merge request gitlab-org/gitlab-ce!30027

The spec is too strict about how many `current_version` should be
called - if the spec is called separately, it's called 3 times, if
all specs run it's called twice.

This is similar to the change done in
