Use CoAP for uploading chunks to Memfault instead of HTTP. Memfault will leverage the exisiting CoAP connection to nRF Cloud, which will forward chunks to Memfault servers. This allows for reuse of the CoAP connection id and socket, to avoid the overhead of a separate DTLS handshake and use of another socket in the modem.

This is blocked on the version bump of the Memfault SDK in NCS (>1.36.0)
