Implement metadata access and function execution

[libc-furiosa]

Add device management API for accessing metadata and running functions. (for https://github.com/furiosa-ai/device-api/blob/b0647e0b2ac27b987df75e07dae1ecf1490d4d55/src/sysfs.rs like https://github.com/furiosa-ai/device-api/blob/b0647e0b2ac27b987df75e07dae1ecf1490d4d55/src/device.rs#L81)

@sukyoungjeong-furiosa First, I'll start with alive, atr_error, heartbeat.

Ok, I'll try establishing the primitives for writable mgmt files and interface functions for them.
