AOSP 11.0 v312

• VoLTE on Mediatek R vendors
• Under-display fingerprint comeback. Partial support on OnePlus Nord2.
• Double-tap to wake on OnePlus Nord2
• Fix fingerprint support on some OPPO/OP devices
• Fix securize while running Magisk in some cases (Thanks @hwti )

--- All those changes (except last one), are because I bought that OnePlus Nord2 from my own money. so if you like this changelog, don't forget to sponsor me
