Implement GetTotalReceivedBytes() for StreamSocket

GetTotalReceivedBytes() returns the number of bytes
read from the network. Currently, only TCPClientSocket
implements GetTotalReceivedBytes().

Tests are in ssl_client_socket_unittest.cc.

Right now GetTotalReceivedBytes() is not plumbed to the
higher layers. Once that's done, this will help us in
precisely computing the network bytes used by a request.
