Subject: [PATCH] [ML] DataFrame Analytics: Regression results view (#49667)

* enable analytics table view link for regression jobs

* add results table component

* can filter for training/testing

* add search functionality to table

* move shared types to analytics types file

* anchor isTraining,predicted,actual columns to left.

* ensure search string persists in search bar input

* show jobStatus badge in results view

* add jobType, status badge to outlier exploration page

* update exploration tests
