face: perform wire format encoding in frontend class

Face::put encodes Data and Nack into wire format before passing to Impl class,
so that Face::put(const Data&) doesn't require the Data to be managed by a
shared_ptr.
For the common case of sending Data without other NDNLPv2 headers, this commit
adds an optimization that the Data is not copied into an LpPacket, but directly
encodes into wire format.
