support different boot partition sizes in aosp_arm64

The different boot images in aosp_arm64 have different partition size
requirements. Add support for defining a partition size associated with
each boot image variant.

This support is limited to aosp_arm64 currently, which is built with
recovery-as-boot.

A previous version of this change did not update the boot-debug image
AVB logic with the required macro for multiple boot partition size
support. This is now required because the aosp-arm64 boot.img is
configured as a chained AVB partition.

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For an outdated reference on Android.mk files, see build-system.html.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