feat(where): Support stored closure (#15697) ...

# Description

- `where` used to be able to filter using stored closures at some point
using a flag.
  > #5955
- This was later removed and `filter` command added to cover the use
case.
  > #7365

This PR once again allows using `where` with closures stored in
variables.

```nushell
let cond = { $in mod 2 == 0 }
1..10 | where $cond
# => ╭───┬────╮
# => │ 0 │  2 │
# => │ 1 │  4 │
# => │ 2 │  6 │
# => │ 3 │  8 │
# => │ 4 │ 10 │
# => ╰───┴────╯

let nested = {cond: { $in mod 2 == 0 }}
1..10 | where $nested.cond 
# => ╭───┬────╮
# => │ 0 │  2 │
# => │ 1 │  4 │
# => │ 2 │  6 │
# => │ 3 │  8 │
# => │ 4 │ 10 │
# => ╰───┴────╯
``` 

This does not interfere with using `$it` or one of its fields as the
condition.
```nushell
[[name state]; [foo true] [bar false] [baz true] [quox false]]
| where $it.state
# => ╭───┬──────┬───────╮
# => │ # │ name │ state │
# => ├───┼──────┼───────┤
# => │ 0 │ foo  │ true  │
# => │ 1 │ baz  │ true  │
# => ╰───┴──────┴───────╯
``` 

This change obsoletes `filter`, deprecate it in the future?
