Improve non-triggered manual action job detail page

Description

We render builds that have been skipped pretty weirdly. This is particularly bad for manual actions since there isn't even a place to trigger the manual action. e.g. https://gitlab.com/markpundsack/docker-example/builds/3631303

Proposal

Not sure what to do, but:

• We should not have a build log
• We should have way to trigger manual actions
• The details in the sidebar should be accurate

Design

• information in sidebar which is not available as the job has not started/been triggered yet has been hidden.
• title bar shows "created by" instead of "triggered by"
• empty state added for
  • manual action needed
  • created, but not run yet svg's:
• graphic-manual-ation.svg
• graphic-no-trigger.svg

note: according to https://gitlab.com/gitlab-org/gitlab-ce/issues/32380 the button can have a disabled state if it needs another manual action first
