Add --directory (-D) flag to ls, list the directory itself instead of its contents (#5970)
* Avoid extending the directory without globs in `nu_engine::glob_from`

* avoid joining a `*` to the directory without globs

* remove checks on directory permission and whether it is empty

The previous implemention of `nu_engine::glob_from` will extend the
given directory even if it containes no glob pattern. This commit
overcomes lack of consistency with the function `nu_glob::glob`.

* Add flag -D to ls, to list the directory itself instead of its contents

* add --directory (-d) flag to ls

* correct the difference between the given path and the cwd

* set default path to `.` instead of `./*` when --directory (-d) flag is true

* add comments

* add an example

* add tests

* fmt
