Since recent kernels seem to limit the number of loopback
devices to 7, we now just mount the required apex files in TWRP.
To mount additional apex files specify TW_ADDITIONAL_APEX_FILES
in your BoardConfig, for example:
TW_ADDITIONAL_APEX_FILES := "apex1 apex2"
To disable Apex in your builds use:
TW_EXLUCDE_APEX := true

We also look to use the loop-control device to identify loop devices.
We only create devices if they don't exist. Modern kernels can have
an option CONFIG_BLK_DEV_LOOP_MIN_COUNT=16 to pre-create the devices.

for android-10
This will support updating the ramdisk to a different
compression format and co-exist with magisk.
We are also cleaning up and removing non android-10
api makefile actions.
We are also moving twrp repacking to its own class. We
check the new ramdisk format and if it's different
we have magisk compress using the new ramdisk format.

This patch uses the loop device to mount files under
/sbin/ from /system/apex in order for the device to
use libraries or other files store inside these files.
Each apex file is mounted over a loop device into a
directory correpsonding to the apex filename under
/sbin/.
Once apex mounting is completed, TWRP will set a
property twrp.apex.loaded to true so that init
can use them as a LD_LIBARY_PATH source.
