Implement completion for the callable fields.
Fixes#14656
PR is opened with basic changes. It could be improved by having a new `SymbolKind` for the callable fields and implementing a separate render function similar to the `render_method` for the new `SymbolKind`.
It could also be done without any changes to the `SymbolKind` of course, have the new function called based on the type of field.
I prefer the former method.
Please give any thoughts or changes you think is appropriate for this method. I could start working on that in this same PR.
chore: remove unused `PhantomData`
This PR removes an unused `PhantomData` in `FileItemTreeId`.
*Note:* I am not sure how this should be implemented, maybe as a type instead of a wrapper struct? I'd be happy to do so if needed 👍
Improve error handling for top-level `let` statements
This commit addresses the issue of excessive and unrelated errors generated by top-level `let` statements. Now, only a single error is produced, indicating that `let` statements are invalid at the top level.

While I'm not really sure if handling a particular case in a special manner is appropriate, it would be good to suppress the excessive number of annoying and unrelated errors.

internal: simplify the removal of dulicate workspaces.
### Summary:
Refactoring the duplicate removal process for `workspaces` in `fetch_workspaces`.
### Changes Made:
Replaced `[].iter().enumerate().skip(...).filter_map(...)` with a more concise `[i+1..].positions(...)` provided by `itertools`, which enhances clarity without changing functionality
### Impact:
This change aims to enhance the duplicate removal process for `workspaces`. This change has been tested on my machine.
Please review and provide feedback. Thanks!
