Add default --empty to handle empty values (#15223) ...

# Description

Adds a new `--empty/-e` flag to the `default` command.

# User-Facing Changes

Before:

```nushell
$env.FOO = ""
$env.FOO = $env.FOO? | default bar
$env.FOO
# => Empty string
```

After:

```nushell
$env.FOO = ""
$env.FOO = $env.FOO? | default -e bar
$env.FOO
# => bar
```

* Uses `val.is_empty`, which means that empty lists and records are also
replaced
* Empty values in tables (with a column specifier) are also replaced.
