Add filter and sort to organization project view

What does this MR do and why?

Related to #409030 (closed)
Designs: #406613 (closed)

The grouptenant scale team is starting to build out an Organization MVC. For more information about what an "Organization" will be see https://docs.gitlab.com/ee/user/organization/

This MR continues to build the Groups and projects page by adding filter and sorting to the page.

A few notes:

• The projects view is currently using a mock GraphQL resolver with mock data.
• The groups view will be built in #409029 (closed)
• The search and sort do not currently change how the GraphQL query is called. This will be implemented in a future MR.
