Resign apks contained in apex

Some apex payload images contain apk files. And these apks need to be
signed during the signing processed when sign_target_files_apks is
called. To support the signing, we can extract the payload and repack
the apex file with the (de)apexer tool. Add the signing support in the
apex_util.

Bug: 146508800
Test: unit tests pass, run sign_apex, sign_target_files_apks

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For an outdated reference on Android.mk files, see build-system.html.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