Get rid of general jobs list view
### Problem

- With the introduction of "pipelines" the "general jobs list view" is no longer used. (Verified by @marin ).
- It provides to little context, compared to pipelines
- This now still takes up an important spot in navigation
- It also has a big red cancel all running jobs button. Separate issue created for that: https://gitlab.com/gitlab-org/gitlab-ce/issues/34665
### Proposal
Get rid of the general jobs list view all together.
I created a separate issue to repurpose this view in a way that makes more sense:
- https://gitlab.com/gitlab-org/gitlab-ce/issues/34664 - [Create inspectable job list view of runner for everyone](https://gitlab.com/gitlab-org/gitlab-ce/issues/34664)
