net: lwm2m: Add support for X509 certificates

Browse source 
Add support for using X509 certificates.
Default settings use ECDSA certificates with SHA256 hash.

When different settings are required clients should overwrite
struct lwm2m_ctx->load_credentials() and
struct lwm2m_ctx->set_socketoptions()
