core: Limit maximum size of an assembled MCTP message

If libmctp receives sequence of fragment MCTP packets and never receives
EOM packet, this will cause heap memory to grow without bounds. This
commit puts an upper cap on maximum MCTP message size. This should
protect us from any malicious device trying to exploiting this.

Also, this prevents overwhelming of the device's resources.
Section 10.1.5 of DSP0236 (v1.3.1) allows configuration of
endpoints to protect its resources.
