[Enhancement] Fill assignment param of bucket shuffle and colocate shuffle for debug

[xinghuayu007]

Proposed changes

When Doris is in debug mode, function Coordinator#traceInstance is used to print the phsical execute plan of a fragment instance for debug. Function Coordinator#traceInstance uses param scanRangeAssignment to print the detail of a fragment. But bucket shuffle join and colocate shuffle join do not fil the param. That will cause debug not work availablely.
This path fill assignment param of bucket shuffle and colocate shuffle for debug.
