fix(ls): make --omit filter npm ls

This makes `npm ls` use the same logic as other commands (eg `outdated`)
when parsing config items that filter the output based on package type.

Previously `--development` and `--production` has special semantics when
used with `npm ls` that were inconsistent with the rest of the CLI. To
achieve the same behavior as these deprecated flags use:

- in place of `--development` use `--omit peer --omit prod --omit optional`
- in place of `--production` use `--omit dev --omit peer`

Fixes #4739
