支持解析启动命令行参数，行为与Linux一致。具体见文档。 bbs链接：https://bbs.dragonos.org.cn/t/topic/362 issue: https://github.com/DragonOS-Community/DragonOS/issues/865 支持了三种参数： - Arg （不带Value的参数） - KV （正常的KV参数） - EarlyKV (在内存管理初始化之前解析） # TODO - 支持在`/proc/cmdline`下面查看内核启动时的命令行参数。 - 支持回调函数，允许更加灵活的设置参数的值（目前用不到，就没写了） Signed-off-by: longjin <longjin@DragonOS.org>

# 该脚本用于将disk_mount目录下的文件写入到disk-${ARCH}.img的第一个分区中，
|
||
# 并在磁盘镜像中安装grub引导程序
|
||
#
|
||
# 用法：bash write_disk_image.sh --bios legacy/uefi
|
||
# 如果之前创建的 disk-${ARCH}.img 是MBR分区表，那么请这样运行它：bash write_disk_image.sh --bios legacy
|
||
# 如果之前创建的 disk-${ARCH}.img 是GPT分区表，那么请这样运行它：bash write_disk_image.sh --bios uefi
|
||
# 通过设置ARCH为x86_64/i386/riscv64，进行64/32位uefi的install，但是请记住该处的ARCH应与run-qemu.sh中的一致
