soc/interconnect/packet: simplify/refactor Packetizer/Depacketizer to keep it simple
...
To avoid complex FSMs, let the synthesis tool do the simplifications when the FSM states are not reachable.

soc/interconnect/packet: add > 8-bit support to Packetizer/Depacketizer
...
With high speed link (10gbps XGMII ethernet for example), stream data_width is generally
> 8-bit which make header/data un-aligned on bytes boundaries. The change allows the
Packetizer/Depacketizer to work on stream with a data_width > 8-bit.
