making ls and du supports rest parameters. (#12327)
# Description
Close: #12147
Close: #11796 

About the change: it make pattern handling into a function:
`ls_for_one_pattern`(for ls), `du_for_one_pattern`(for du). Then
iterates on user input pattern, call these core function, and chaining
these iterator to one pipelinedata.
