Whenever we create pipelines we need to call `ensure_project_iid!` on
them before saving them otherwise we trigger a write to the
`internal_ids` table in the transaction for saving the model which
causes as cross-database modification.

These cases are all false positives because we already call
`ensure_project_iid!` everywhere we create a pipeline in real
application code.

At present all the spec violations we found are false positives caused
by the fact that `ensure_project_iid!` is not called on the pipeline
before saving. We can remove many of them by just doing this in the
`after(:build)` for the `ci_pipeline` factory.

There are still a couple in `atomic_internal_id_shared_examples` but
these are specs that are explicitly trying to do things in transactions
and rolling things back so they aren't really representative of real
application code so it seemed easier to just wrap these in `allow_...`
for now and extract an issue if we ever want to actually refactor these
tests. It may be tricky to refactor them because they are used for other
models where these transaction behaviours being tested do indeed matter.

Code Improvements for Projects :: Infra :: Google Cloud

See merge request gitlab-org/gitlab!75295

- Feature flag `incubation_5mp_google_cloud` bound to Project
  This allows for easier testing on gitlab.com where the feature
  flag may be enabled for select projects.

- `service_accounts` is an active route for `google_cloud` menu item
  This expands the appropriate project sidemenu item when creating
  a service account

- Introduce a top level `app.vue` component
  Achieves consistency with a majority of frontend code in the repo
  Where a single route with a single entry point serves multiple templates
  Instead of routing the frontend in `index.js` use a top level component
  to render the appropriate `screen`
