Split ANGLE supported and enabled into different Makefiles.

ANGLE binaries should be added to the PRODUCT_PACKAGES instead. This
patch also splits the angle.mk to angle_supported.mk and
angle_default.mk so that when a device just wants to ship ANGLE binaries
to coexist with native GLES drivers, it only needs to inherit the
angle_supported.mk and when a device wants to ship ANGLE as the default
system GLES drivers, it only needs to inherit the angle_default.mk. When
ANGLE is the default system GLES driver, make sure persist.graphics.egl
is defined so that ANGLE is loaded properly.

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For an outdated reference on Android.mk files, see build-system.html.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