455b725248 Deprecated AUTO_ADD_TRY_UMOUNT_FOR_BIND_MOUNT, the leftover add_sus_mount cli and umount_for_zygote_system_process 
Reason:
 - AUTO_ADD_TRY_UMOUNT_FOR_BIND_MOUNT is also causing a bit more performance overheads and still it cannot catch all the sus mounts in all situations. Actually it can easily be done in boot-completed.sh, and it should be more accurate, see module templates for more details.

- Official KernelSU also allows ksud to add custom path to try_umount list as well, users can use their own way to add only the desired sus mounts to try_umount list, but remember to disable susfs ADD_TRY_UMOUNT in kernel if users want to use the official one.

- There are less use cases for umount_for_zygote_system_process, and sometimes enabling this may cause bootloop with some modules enabled, instead user can use busybox nsenter to umount the sus mounts for specific process later by themmselves.
