Add BUILD_BROKEN_TREBLE_SYSPROP_NEVERALLOW

A new sysprop neverallow rules are mandatory only for devices launching
with R or later. For devices already launched, neverallow rules can be
relaxed with adding following line to BoardConfig.mk:

BUILD_BROKEN_TREBLE_SYSPROP_NEVERALLOW := true

Bug: 131162102
Test: Set PRODUCT_SHIPPING_API_LEVEL := 30 and try building with
changing some system_public_prop to system_internal_prop
Test: m cts sepolicy_tests

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
