Read from standard input in rm (#3763)

Browse Source 
* Read from standard input in `rm`

With this change, rm falls back to reading from the standard input if no
arguments are supplied. This leads to more intuitive pipes as seen in
https://github.com/nushell/nushell/issues/2824

 ls | get name | sort-by | first 20 | each {rm $it} becomes
 ls | get name | sort-by | first 20 | rm

* [Fix] Run cargo fmt, make files a rest parameter, and fix cargo build warnings

* [Fix] Fix clippy suggestions
