fpga: lib: Update xport_sv

Browse Source 
- Detect dropped words at the dispatch level. This prevents
   an overflow on CHDR from block CPU.
 - Dropped packets are recorded as CPU or CHDR drop count
 - Refactor to put chdr_xport_adapter.sv in different clock
   domain to improve timing
 - Unwrinkle tkeep/trailing transitions
