Don't use old VNDK and SystemSDK versions for new devices

We need to prevent vendors from using old VNDK and SystemSDK versions
for newly launched device. Otherwise, deprecating old versions of the
APIs would be really difficult.

Specifically, it is enforced that

PRODUCT_SHIPPING_API_LEVEL <= BOARD_VNDK_VERSION

PRODUCT_SHIPPING_API_LEVEL <= min(BOARD_SYSTEMSDK_VERSIONS)

Bug: 72126206
Test: manually setting BOARD_VNDK_VERSION to 24 in
device/google/wahoo/BoardConfig.mk and choosecom to walleye
Test: m -j shows an error on BOARD_VNDK_VERSION
Test: BOARD_SYSTEMSDK_VERSION="25 26" m -j shows an error on
BOARD_SYSTEMSDK_VERSION

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For an outdated reference on Android.mk files, see build-system.html.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.
