Anton Hansson 40c4773288 Split GSI and mainline board configs 
Make the mainline board config only import a subset of the GSI
options. The current set of attributes is the minimal set to
keep mainline_system_arm64 building, as well as not producing
any diffs in the current set of files in /system. It's possible
we'll need to move a few more over, but we'll do that on a
case-by-case basis.

Make the GSI config inherit the mainline one. The only diff for GSI
should be the addition of BOARD_USES_SYSTEM_OTHER_ODEX.

Bug: 119911662
Test: build mainline_system_arm64

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For an outdated reference on Android.mk files, see build-system.html.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