af01a36296 Refactor magic mount to support overlayfs 
Previously, magic mount creates its own mirror devices and mount
mirror mount points. With these mirror mount points, magic mount
can get the original files and directory trees. However, some
devices use overlayfs to modify some mount points, and thus after
magic mount, the overlayed files are missing because the mirror
mount points do not contain the overlayed files. To address this
issue and make magic mount more compatible, this patch refactors
how magic mount works.

The new workflows are as follows:
1. make MAGISKTMP a private mount point so that we can create the
   private mount points there
2. for mirror mount points, we instead of creating our own mirror
   devices and mount the mirror mount points, we "copy" the
   original mount points by recursively mounting /
3. to prevent magic mount affecting the mirror mount points, we
   recursively set the mirror mount points private
4. to trace the mount points we created for reverting mounts, we
   again make the mirror mount points shared, and by this way we
   create a new peer group for each mirror mount points
5. as for tracing the newly created tmpfs mount point by magic
   mount, we create a dedicated tmpfs mount point for them, namely
   worker mount point, and obviously, it is shared as in a newly
   created peer group for tracing
6. when reverting mount points by magic mount, we can then trace
   the peer group id and unmount the mount points whose peer group
   ids are created by us

The advantages are as follows:
1. it is more compatible, (e.g., with overlayfs, fix #2359)
2. it can mount more partitions for which previous implementation
   cannot create mirror mount points (fix #3338)

No kernel repack if it isn't patched at all 
It turns out that decompressing and recompressing the kernel is enough to break booting on many devices that use MT6763.

Refactor sepolicy.rules resolve 
We resolve available partitions for sepolicy.rules when patching
boot and bind mount the partition by magiskinit.

For older devices, the previous logic won't work because the part name
is never readable.

Inject binaries into /system if sbin not accessible 
Some Android 11+ devices have the /sbin partition but not accessible by the global shell (`PATH` doesn't contain `/sbin`). Not only custom ROMs but also some stock ROMs have the same behavior so I believe it is something we need to deal with.

8423dc8d63 Later check persistent_properties 
`daemon_entry` calls `getprop` which initializes sysprop impl and checks whether we need to load persistent property file. On FDE devices, magiskd starts before /data is actually decrypted, and the check always fails. Thus `persist_getprop("persist.sys.safemode")` will always fail.

1f8c063dc6 Fix booting into recovery with Android 13 GKI kernels 
With Android 13 GKI kernels, the boot partition has no ramdisk, so
Magisk constructs one from scratch. In this scenario, there's no backup
init binary at /.backup/init. For normal boot, magiskinit will symlink
/init -> /system/bin/init if needed. This commit implements the same
for booting into recovery. Before, magiskinit would just exec itself
over and over again because it couldn't restore the backup init.

7505599ea0 Skip invalid slot_suffix argument 
Many Amlogic devices (e.g. FireTV 2nd gen Cube, Vero 4k+, MI Smart Speaker, etc.) are A-only with androidboot.slot_suffix=normal argument. I think "normal" actually means A-only in this case so just ignore it.

134508193d Mock selinuxfs load with regular file 
The hijacked load node does not need to be a FIFO. A FIFO is only
required for blocking init's control flow, which is already achieved
by hijacking the enforce node.
