Replace the binary/pod package with binary/any.

There were concerns with performance hit encoding and decoding took with
the introduction of the POD package:
  https://android-review.googlesource.com/#/c/157320/

To address this, the pod package has been replaced with any, which
as well as supporting POD types, can box binary.Object types.
The wrapper object can be encoded using Variant for POD-efficent
encodings while still encoding Objects as references (as the wrapper
uses Object() internally).

Added new schema type to support anys.
