extension_api: Expose preferred_line_length in LanguageSettings (#52175)
Closes #21822

## Context

Exposes `preferred_line_length` from `AllLanguageSettings` to the
Extension
API's `LanguageSettings` struct. Currently only `tab_size` is available
to
extensions, which prevents language extensions (e.g. Dart) from reading
the
user's preferred line length and forwarding it to their language server
(e.g. as `dart.lineLength`).

## How to Review

Small change — follow how `tab_size` is plumbed through:
1. WIT definition (`language-settings` record)
2. `extension_api` Rust struct
3. Host-side bridge conversion

The new field follows the exact same pattern.
