Related to: #3686
Fixes #3812

This PR:

• Implements a basic Table data model.
  • This modal does not have stores for properties that can be updated such as name, description, etc., for the sake of speed. We will be updating it after Beta.
• Implements the Permissions modal -> 'Share' tab for tables.
• Hides the 'Share' button for public sharing in both Table and Exploration Page
