[client] Move some sys info to static place (#4446)

Browse Source 
This PR refactors the system information collection code by moving static system information gathering to a dedicated location and separating platform-specific implementations. The primary goal is to improve code organization and maintainability by centralizing static info collection logic.

Key changes:
- Centralized static info collection into dedicated files with platform-specific implementations
- Moved `StaticInfo` struct definition to the main static_info.go file
- Added async initialization function `UpdateStaticInfoAsync()` across all platforms
