mac: Add metrics for fullscreen entry.

A histogram entry is emitted each time a browser window enters fullscreen. Each
entry has 3 associated parameters:
  - Whether the mechanism used was AppKit or Immersive.
  - Whether the window was on a primary or secondary screen.
  - Whether the "Displays have separate spaces" option in mission control was
  enabled.
