Enable profile based boot image by default

Use profile based boot image instead of the compiled classes version.

Results using profile from ag/2815407
Storage savings:
Boot art+vdex+oat size: 78305556->61539326 (-17MB)

New system server profile has more methods (1.5MB -> 4MB oat) since it
has more coverage from use cases.

Ram savings (sample averages for CUJ test):
Average PSS of 3 runs (~100 samples total):
.Boot_vdex: 9359K -> 9902K
.oat_mmap: 21857K -> 13372K
.Heap: 29779K -> 29483K
.Boot_art: 15736K -> 18096K
.LinearAlloc: 9112K -> 8965K
Total PSS: 85846K -> 79819K (-6MB)

Average pages read from flash (512MB device) for CUJ tests (3 samples):
1508MB -> 1183MB

Bug: 37966211
Test: make and flash

(cherry-picked from commit bf9023ae7a0573dc6473ebe8ca15d5516d4a649d)

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For an outdated reference on Android.mk files, see build-system.html.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