fpga: rfnoc: Add support for 512-bit CHDR widths

Browse Source 
This fixes the rfnoc_null_src_sink, chdr_crossbar_nxn, and
chdr_stream_endpoint blocks so that wider CHDR widths are properly
supported. It also updates PkgChdrBfm to able to properly test these
blocks. The testbenches have been updated to test both 64 and 512-bit
widths.
