Android 12 for Poco X3/X3 NFC

Based on Android Open Source Project (AOSP 12.0.0_r13), with inbuilt gapps, pixel goodies and my custom feature additions & tweaks. Everything is working well to be used as a daily driver. Keep in mind that this is still a beta build, there might be unexpected bugs. These builds are based on OSS vendor, similar to WaveOS. QuicksilveR kernel is included.

* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
