Rebase to hybris 18.1

[000exploit]

LineageOS 16.0 is no longer supported and can't be downloaded from official source, all other unofficial builds are incompatible and don't includes toybox. Btw rebase to never library can fix some problems, if they are.

Sorry, the most I'll do is 17.1 when I find the time to work on this again. This is simply because the OEM provided drivers for Android kernel never got upgraded past Android 10 so there's no point in pouring in so much effort every time a new LineageOS version appears. Besides, even right now hybris-18.1 isn't properly supported on SFOS side with issues such as no call audio on the few devices that do use it currently with a bunch of required additional local patches.

I'll figure out some solution that lets you boot e.g. Android 12 ROM in dual-boot as the A10 firmware (modem etc.) from OnePlus would still be used for both in the end as it has to be signed by 1+, probably will let you place some system.img and vendor.img in the rootfs that will be mounted or similar.
