Add new operators has and not-has (#14841)

# Description
This PR add 2 new operators, `has` and `not-has`. They are basically
`in` and `not-in` with the order of operands swapped.

Motivation for this was the awkward way of searching for rows that
contain an item using `where`

```nushell
[[name, children]; [foo, [a, b, c]], [bar [d, e, f]]]
| where ("e" in $it.children)
```
vs
```nushell
[[name, children]; [foo, [a, b, c]], [bar [d, e, f]]]
| where children has "e"
``` 

# User-Facing Changes
Added `has` and `not-has` operators, mirroring `in` and `not-in`.
