refactor(completion, parser): move custom_completion info from Expression to Signature (#15613)

Browse Source 
Restricts custom completion from universal to internal arguments only.

Pros:
1. Less memory
2. More flexible for later customizations, e.g. #14923 

Cons:
1. limited customization capabilities, but at least covers all currently
existing features in nushell.

# Description

Mostly vibe coded by [Zed AI](https://zed.dev/ai) with a single prompt.
LGTM, but I'm not so sure @ysthakur 

# User-Facing Changes

Hopefully none.

# Tests + Formatting

+3

# After Submitting
