Updated Packet++ headers to use `override` and Cpp type casts.

[Dimi1010]

• Updated classes in Packet++ to use override specifier.
• Updated empty destructors to use = default instead of {}
• Updated many C casts to Cpp casts in Packet++ headers.
• Removed missingOverrides cppcheck suppression from everywhere except Examples and Pcap++ as those are the only modules that currently raise override warnings.
