Move "Macros" to a first-class application

Summary:
This is mostly to unblock D3547.

  - Move "Macros" to a first-class application called "Macros".
  - After D3547, this application will also house "Memes" (macros with text on them).
  - This will also make them easier to find; the top navigational query I field is "where are image macros?" nowadays, since it's not intuitive they're part of files.
  - This makes some of the UI mobile-aware but doesn't set the `device` flag yet, since there are still some missing pieces.
  - I'll separate storage out and continue modernizing the UI as we unblock and integrate D3547.

Test Plan: Created, edited and deleted macros. Viewed files.
