[rust-api-parser] Update parser to have Stable Line IDs

[HarshaNalluru]

Enhance Rust API Parser with Stable Line IDs

• Introduced lineIdMap to map item IDs to stable, meaningful identifiers rather than relying on the dynamic rustdoc ids.
• Updated updateReviewLinesWithStableLineIds to ensure consistent review line IDs across modules and external references.
• Preserved the linking between items in the api view rendering
• This is required to show meaningful diff between api views
• Other changes include formatting and minor refactoring

• azure_messaging_eventhubs

Pull Request Overview

This PR updates the Rust API parser to support stable line IDs by introducing a persistent mapping via lineIdMap and updating all relevant processing functions accordingly. Key changes include:

• Introducing and integrating the new lineIdMap into item processing functions.
• Updating functions such as registerExternalItemReference, processUse, and various process* functions to use consistent line IDs.
• Minor refactorings and formatting improvements to support the new stable line IDs.

• [nitpick] The variable 'linedId' is inconsistent with the naming convention used elsewhere (e.g. 'lineId'). Consider renaming it to 'lineId' for consistency across the codebase.

const linedId = item.id.toString();

A couple of questions/nits, but I see nothing blocking.
