wireprotov2: define type to represent pre-encoded object

An upcoming commit will introduce a caching layer to command
serving. This will require the ability to cache pre-encoded data.

This commit introduces a type to represent pre-encoded data and
teaches the output layer to not CBOR encode an instance of that
type.

Differential Revision: https://phab.mercurial-scm.org/D4772

Tests for wire protocol version 2 exchange.
Tests in this file should be folded into existing tests once protocol
v2 has enough features that it can be enabled via #testcase in existing
tests.
