Angular Component Migration

[JamesHollyer]

Motivation for features / changes

The legacy components are being deprecated. This is a big step in moving to the new components

Technical description of changes

This was done with a complicated find and replace which included manual pruning. After the find and replace the only other changes are in the mat-slider components as the new mat-sliders have a completely different structure with the thumb as a child component. This mat-slider change in the image card allowed for a cleanup of some weird logic.

Significantly I also change the mat.all-legacy-component-themes call to mat.all-component-themes in the _tb_theme.template.scss file.

This PR causes a lot of styling issues which will need to be resolved before syncing or releasing.
