Implement trackedArray(data, { equals, description })

[NullVoxPopuli]

RFC: emberjs/rfcs#1068

Changes from the tracked-built-ins implementation (as described by the RFC)

• use tags directly, don't use cache / tracked-storage apis (these don't exist anyway)
• defaults to Object.is for the equals function
• has overridable equals function
  • to get tracked-built-ins behavior back, you set equals: () => false
• description is currently unused, but @wycats has plans -- description is meant for debugger hints
