• use the llcppg.cfg 's libs as the LLGoPackage link const
• In the current project, we don't care about the absolute paths of header files. For an individual header file, its include path serves as a unique identifier and is used to generate its name (e.g., sys/dirent.h -> sys_dirent.go, sys/_pthread/_pthread_types.h -> sys__pthread__pthread_types.go)._types.h -> X_types.go
• remove prefix only in llcppg'package 's include file

• 更统一的类型名生成处理逻辑

文件依赖处理

llcppg.cfg 增加一个新的配置项
deps 用于指明当前转换工程依赖了哪些已经转换完毕的llgo c package

{
    "deps":[
        "github.com/goplus/llgo/chore/gogensig/convert/testdata/stdint"
    ]
}

读取这个对于一个llcppg的处理完毕的工程，配置项中对应的标准路径，也指明当前转换完成的包是来自于哪几个标准搜索路径，比如我需要引用一个stdint这个包的时候，之前这个stdint是转换来自对应的头文件，那么在当前引用了这个stdint包的时候，根据其include就可以直接跳过那些头文件

{
    "include":[
        "sys/_types/_int8_t.h",
        "sys/_types/_int16_t.h",
        "sys/_types/_int32_t.h",
        "sys/_types/_int64_t.h",
        "sys/_types/_u_int8_t.h",
        "sys/_types/_u_int16_t.h",
        "sys/_types/_u_int32_t.h",
        "sys/_types/_u_int64_t.h"
    ]
}

对于转换完成的包新增一个配置项 llcppg.pub
用于存放当前包中完成映射的符号名，左边为C中的符号名，右边为转换完毕后Go中的名称，对于引用该包的转换工程一旦访问到这些名称，就可以直接从该包中获取对应的类型

int8_t Int8_t
uint8_t Uint8_t
u_int8_t U_int8_t
int16_t Int16_t
uint16_t Uint16_t
u_int16_t U_int16_t
u_int64_t U_int64_t

在文件的依赖处理中，则由头文件标准引用路径作为key，具体生成逻辑参考 #853
