Data view: Add support for resizable table columns

[andrew-ronaldson]

Design work to enable patternfly/react-data-view#464

Problem

Products and customers report a desire for more flexibility when looking at data in a table. All columns within a table are set predefined widths that can lead to truncation or wrapped content in multiple lines.

Current capabilities

• Horizontal scrolling in tables (with/without sticky columns)
• A column management modal to add/remove and reorder columns

Goal

The design team will collect feedback and provide recommendations for implementation. Once this task is completed we will need issues in the design kit design kit and documentation for the dataview extension.
