Roland Levillain c7c4a766f0 Reland "Remove Core Library JARs from /system/framework." 
These JARs are part of the ART APEX, and are now located in
`/apex/com.android.art/javalib`. Remove the supernumerary copies in
`/system/framework` and save ~11 MiB on the system partition.

This change no longer breaks coverage builds, as module
`jacocoagent` has been removed from `TARGET_CORE_JARS` in CL
https://android-review.googlesource.com/c/platform/build/+/1151464.

This reverts commit 7c39368927.

Test: Device boot test
Test: Check that:
        export EMMA_INSTRUMENT=true
        && unset EMMA_INSTRUMENT_STATIC
        && m installclean
        && m systemimage
      generates a system image that contains these files:
        /system/framework/apex-jacocoagent.vdex
        /system/framework/boot-jacocoagent.vdex
        /system/framework/jacocoagent.jar
        /system/framework/<arch>/apex-jacocoagent.art
        /system/framework/<arch>/apex-jacocoagent.oat
        /system/framework/<arch>/apex-jacocoagent.vdex
        /system/framework/<arch>/boot-jacocoagent.art
        /system/framework/<arch>/boot-jacocoagent.oat
        /system/framework/<arch>/boot-jacocoagent.vdex
Test: Run test ATP test avd/avd_boot_health_check on build target

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For an outdated reference on Android.mk files, see build-system.html.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