net: lwm2m: introduce lwm2m context structure

Browse source 
The LwM2M library does not use net_app APIs internally.  To help
this effort let's establish a user facing structure "lwm2m_ctx"
(similar to http_client_ctx and mqtt_ctx) and start it off by
wrappering the net_context structure.

Future patches will add user setup options to this structure and
eventually remove the net_context structure in favor of a net_app_ctx.
