Use apex_available property

Use apex_available property to prevent modules that are only for the ART
apex from being used outside of the APEX.

Bug: 129006418
Test: m
Test: m libnativeloader doesn't install anything. (because it doesn't
have "//apex_available:platform".
Test: Add "libnativeloader" to shared_libs of "libvndksupport" which is
installed to /system/lib. Then the build fails with following error:

  error: system/core/libvndksupport/Android.bp:3:1: module
  "libvndksupport" variant "android_arm_armv8-a_core_shared": depends on
  //art/libnativeloader:libnativeloader which is not visible to this
  module

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For an outdated reference on Android.mk files, see build-system.html.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