refactor: prefetch exports info data of getters part 3

[LingyuCoder]

Summary

• Introduce PrefetchedExportsInfoUsed to prevent fetching unnecessary named exports which caused the performance degression. Then modify the param of get_used_name to enum to support PrefetchedExportsInfoUsed for fast path when the names list is empty.
• Unify the way of accessing properties. Set all properties of ExportsInfoData/ExportInfoData to private and provide getter/setter to access them.
• Move get_target/find_target related functions to exports/target.rs.
• Move referenced export related functions to exports/referenced_export.rs, and also rename process_export_info to collect_referenced_export_items to make the function name more informative

This pull request introduces multiple changes across several files to enhance the handling of export information and improve code efficiency. The updates include replacing direct field access with getter methods, introducing new enums for clarity, and optimizing hash computation. Below is a breakdown of the most important changes grouped by theme.

Enhancements to Export Information Handling:

• Replaced direct field access in ExportInfoData with getter methods like info.name() and info.global_used() for better encapsulation and maintainability in crates/rspack_core/src/exports/export_info_getter.rs. [1] [2] [3] [4] [5]
• Updated get_used_name and get_used methods to use the new getter methods, ensuring consistent access patterns. [1] [2]

Code Simplification and Refactoring:

• Introduced GetUsedNameParam::WithNames for better parameter clarity in ExportsInfoGetter::get_used_name calls. [1] [2] [3]
• Replaced FindTargetRetEnum with FindTargetResult for more descriptive enum variants in impl ConcatenatedModule.

Prefetching and Hash Optimization:

• Replaced prefetch calls with prefetch_used_info_without_name or get_prefetched_exports_info to improve export information retrieval and reduce unnecessary data fetching. [1] [2] [3] [4] [5]
• Optimized hash computation by batching module graph hash calculations into a single loop, reducing redundant operations. [1] [2]

Enum and API Updates:

• Updated ExportInfoGetter methods to utilize the new getter-based API for accessing export details, aligning with the encapsulation changes. [1] [2]
• Improved readability and maintainability by replacing old enums with more descriptive ones, such as FindTargetResult.

Dependency and Import Adjustments:

• Adjusted imports across files to include new dependencies like PrefetchExportsInfoMode and GetUsedNameParam. [1] [2] [3]

These changes collectively improve the codebase's clarity, performance, and maintainability.

I can see there are many similar pattern like this, a few lines of code refactored to many lines of code, can we have a facade function for this pattern, to make more cleaner at the call site, and more easier to use

[LingyuCoder]

Ok

[ahabhgk]

Generally looks good to me, a suggestion can resolve in the future PR
