Function microvmi::capi::microvmi_envlogger_init

#[no_mangle]
pub unsafe extern "C" fn microvmi_envlogger_init()

This API allows a C program to initialize the logging system in libmicrovmi. This simply calls env_logger::init() Usually, it’s the library consumer who should add this Rust crate dependency, however, with a C program, we provide this workaround where we provide an API to do just that.
