217 implement proccpuinfo like device

[AlixANNERAUD]

This pull request introduces a new virtual CPU information device for both native and WebAssembly (WASM) environments, exposes it in the virtual file system, and integrates it into the system's initialization and the Settings application's About tab. This enables users and applications to retrieve standardized CPU information (such as model, core count, and architecture) via a virtual file, improving system introspection and portability.

New CPU Information Device

• Added CpuInformationsDevice implementation for both native (drivers/std/src/devices/cpu.rs) and WASM (drivers/wasm/src/devices/cpu.rs) targets, providing a /devices/cpu/informations character device that outputs formatted CPU details. The native version parses /proc/cpuinfo when available, while the WASM version uses browser APIs to estimate core count. Both fallback gracefully to "unknown" when data is missing. [1] [2]
• Updated device module exports to include the new CPU device in both native and WASM drivers. [1] [2]

Virtual File System Integration

• Modified system initialization in native, WASM, and test environments to create the /devices/cpu directory and mount the new CpuInformationsDevice at /devices/cpu/informations. [1] [2] [3] [4] [5] [6]

Settings Application Enhancement

• Updated the Settings application's About tab to asynchronously read from /devices/cpu/informations and display a summary of the CPU model, core count, and architecture, improving the user's visibility into system hardware. [1] [2] [3]

Testing and Robustness

• Included comprehensive unit tests for the new device implementations, covering parsing, formatting, reading with offsets, and error handling for unsupported writes. [1] [2]
