Android 13 support

[ypid]

Just to let you know, I will started on Android building/(development) with the intent to get Android 11 supported. A bit late I know but I had to get my build machine up and running. My philosophy on basing on https://grapheneos.org/ is that I would like to understand all patches I apply to AOSP, so I guess I will only take a small set of patches from GrapheneOS for now.

I guess it makes most sense for me to update #40 to Android 11 and then get this PR eventually ready to be merged.

Depends on: hashbang/aosp-build#26

Edit: Android 12 is supported.
