Add BOARD_SUPER_IMAGE_IN_UPDATE_PACKAGE flag.

When set, product-img-tag.zip contains super.img instead of individual
user images from target files. For virtual devices, super.img is needed
to boot the device, but individual user images aren't needed.

Test: on A/B DAP, with flag set:
     - m updatepackage and look at img.zip
     - img_from_target_files
     both have super.img and not system / vendor / system_other
Test: on non-A/B DAP, with the flag set:
     - m updatepackage and look at img.zip
     - img_from_target_files
     both have super.img and not system / vendor
Test: on A/B retrofit, with the flag set:
     - m updatepackage and look at img.zip
     - img_from_target_files
     both have super_*.img and system_other.img, but not system / vendor

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For an outdated reference on Android.mk files, see build-system.html.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