feat(components): Add action menu to FormatFile

[taylorvnoj]

Motivations

This is a POC to see what an actions menu would involve on FormatFile.

There may be more actions than just delete moving forward on the FormatFile component (ex. download).

Instead of adding an onDownload prop which is just another callback, we can open up a menu to allow for endless customizable options in the future.

Added

• added a FormatFileMenu component within FormatFile

Not done yet/future considerations

• focus state/accessibility/keyboard events
• deprecating onDelete
• should there be a menu even if there's only one action? Right now the logic is if actions?.length > 0
• further styling (colour of text on destructive, etc)
• size of the menu button while compact & base props are in effect

Changes can be tested via Pre-release
