[Cloud Security][Findings++ Phase 1] Create common table component using unified-data-table package

[mitodrummer]

Motivation

Yuliia is currently working on extracting the discover grid into a package called "unified-data-table". This component checks all the boxes we need for the findings/vuln data grids, and more importantly is a path to avoid having to re-invent the wheel and create a completely different experience from the rest of Kibana.

PR for unified-data-table package: https://github.com/elastic/kibana/pull/163211/files#diff-1cb21a17baad332c946437e62ef2bef10ba53741eb74385a245d26242d462360

Definition of done

• Create a new common "cloud security data grid" component that uses 'unified-data-table' package and abstracts all common code related to tables across our solutions. The interface should be as lean as possible to make adoption in other pages a breeze.
• A re-useable generic interface should be created to define the set of default columns, display names, and custom cell renderers.
• As part of this ticket the "latest_findings" page should adopt this new component/hook/interface.
• Ensure testing happens for both ESS and serverless modes of operation

Out of scope

• persistence of column layout
• fields api to dynamically select columns from derive fields in doc, or runtime fields.
• other tables to be updated in separate tickets.
