du: add -l/--long flag, remove -a/--all flag (#14407)

# Description
Closes:  #14387 
~To make it happen, just need to added `-l` flag to `du`, and pass it to
`DirBuilder`, `DirInfo`, `FileInfo`
Then tweak `impl From<DirInfo> for Value` and `impl From<FileInfo> for
Value` impl.~

---

Edit: this PR is going to:
1. Exclude directories and files columns by default
2. Added `-l/--long` flag to output directories and files columns
3. When running `du`, it will output the files as well. Previously it
doesn't output the size of file.

To make it happen, just need to added `-r` flag to `du`, and pass it to
`DirBuilder`, `DirInfo`, `FileInfo`
Then tweak `impl From<DirInfo> for Value` and `impl From<FileInfo> for
Value` impl.

And rename some variables.

# User-Facing Changes
`du` is no longer output `directories` and `file` columns by default,
added `-r` flag will show `directories` column, `-f` flag will show
`files` column.
