Apply Compliance Framework

Follow up from discussion in this thread #379038 (comment 1168394989)

Adds the ability to select projects within the new compliance framework report, and apply a framework to these selections.

User can individually select projects, or select all projects shown on the current page of results.

Selecting all projects over all pages as shown in the design will be handled separately in #388484
