实现unified-init库，支持收集初始化函数到一个数组，并统一初始化 (#474)

* 添加“统一初始化”的过程宏，并把SystemError独立成crate

* 使用unified-init来初始化fbmem

* 更新workflow，增加内核自动化静态测试

+# unified-init 统一初始化库
+
+:::{note}
+本文作者：龙进 <longjin@DragonOS.org>
+
+2023年12月25日
+:::
+
+## 1. 简介
+
+该库位于`kernel/crates/unified-init`中.
+提供统一初始化宏,用于将函数注册到统一初始化列表中. 便于统一进行初始化.
+
+需要注意的是，初始化器的数组是no_mangle的，因此其命名应当遵守`模块_初始化器`的规则，防止重名导致意想不到的错误.
+
+
+## 2. 用法
+
+
+```rust
+use system_error::SystemError;
+use unified_init::define_unified_initializer_slice;
+use unified_init_macros::unified_init;
+
+/// 初始化函数都将会被放到这个列表中
+define_unified_initializer_slice!(INITIALIZER_LIST);
+
+#[unified_init(INITIALIZER_LIST)]
+fn init1() -> Result<(), SystemError> {
+   Ok(())
+}
+
+#[unified_init(INITIALIZER_LIST)]
+fn init2() -> Result<(), SystemError> {
+   Ok(())
+}
+
+fn main() {
+    assert_eq!(INITIALIZER_LIST.len(), 2);
+}
+
+```
+
+## 3.开发
+
+需要测试的时候可以在`main.rs`写测试代码，
+然后在当前目录执行 `cargo expand --bin unified-init-expand`
+就可以看到把proc macro展开后的代码了.
