Update Admin Area's Runners Page UI

This change enables a new version of the Admin Area's Runners Page UI to
match GitLab design guidelines and become consistent with other areas
of the GitLab UI.

This UI provides faster loading times when searching runners and
prevents users from immediately displaying their instance registration
token on the screen.

The change in UI is done by setting the feature flag
"runner_list_view_vue_ui" to enabled by default.
