add ability to set metadata (#12564)
# Description

This PR adds the ability to set metadata. This is especially useful for
activating LS_COLORS when using table literals.

You can also set the filepath metadata, although I'm not really user how
useful this is. We may end up removing this option entirely.
```nushell
❯ "crates" | metadata set --datasource-filepath $'(pwd)/crates' | metadata
╭────────┬───────────────────────────────────╮
│ source │ /Users/fdncred/src/nushell/crates │
╰────────┴───────────────────────────────────╯
```

No file paths are checked. You could also do this.
```nushell
❯ "crates" | metadata set --datasource-filepath $'a/b/c/d/crates' | metadata
╭────────┬────────────────╮
│ source │ a/b/c/d/crates │
╰────────┴────────────────╯
```

The command name and parameter names are still WIP. We could change
them.

There are currently 3 kinds of metadata in nushell.
```rust
pub enum DataSource {
    Ls,
    HtmlThemes,
    FilePath(PathBuf),
}
```

I've skipped adding `HtmlThemes` because it seems to be specific to our
`to html` command only.
