c38b826abf Skip overlayfs for post-fs-data mount
adb remount will introduce overlayfs for /system and /vendor, we should
skip mounting as overlayfs. This also helps us support overlayfs Magisk
later.

e184eb4a23 Fix UB of loading modules
- The lambda here infers its return type as `std::string`,
  and since `info` is `const`, the labmda copies `info.name`
  and returns a `std::string&&`. After captured by the
  `std::string_view`, the `std::string&&` return value
  deconstructs and makes `std::string_view` refers to a
  dangling pointer.

61783ffc82 Prevent original libselinux.so to be unmounted
libselinux.so will be unmounted when magiskd starts. If magiskd restarts (like it died before boot completed), the files we want to unmount is the original files because the modified files is unmounted in previous start, which will causes many crashes due to missing libselinux.so.

c0a2e3674c Reset file context from adb_data_file
In some cases (like weird ROMs that allow init to relabel context from system_file), module files will have an incorrent context, which will causes module not working properly.

44f005077d Don't copy sepolicy.rule to /persist on boot
* This seems to be a logic that has been abandoned for a
   long time. Now we automatically choose which partition
   to store sepolicy.rule. Furthermore, touching /persist is
   what we should avoid doing whenever possible.

95c964673d Initialized _root properly
Fix #4204

`_root` is uninitialized for non-root nodes. And it will cause `module_node::mount` fail because it uses `root()`. Once the bug is triggered, signal 11 is received but Magisk catch all signals and therefore stuck forever.

16e4c67992 Significantly broaden sepolicy.rule compatibility
Previously, Magisk uses persist or cache for storing modules' custom
sepolicy rules. In this commit, we significantly broaden its
compatibility and also prevent mounting errors.

The persist partition is non-standard and also critical for Snapdragon
devices, so we prefer not to use it by default.

We will go through the following logic to find the best suitable
non-volatile, writable location to store and load sepolicy.rule files:

Unencrypted data -> FBE data unencrypted dir -> cache -> metadata -> persist

This should cover almost all possible cases: very old devices have
cache partitions; newer devices will use FBE; latest devices will use
metadata FBE (which guarantees a metadata parition); and finally,
all Snapdragon devices have the persist partition (as a last resort).
