Always check VNDK variant identicalness

Previously, we only check VNDK core and vendor variants are identical
when a VNDK library is not declared to have different variants AND the
target has TARGET_VNDK_USE_CORE_VARIANT set.  Therefore, it is fairly
easily to break a TARGET_VNDK_USE_CORE_VARIANT target as it needs to be
tested explicitly.

This change uses the new LOCAL_CHECK_SAME_VNDK_VARIANTS and expands the
check to run regardless of TARGET_VNDK_USE_CORE_VARIANT.  Also adds
support for VNDK-in-product.

Bug: 145157349
Test: Build success for targets with and without
      TARGET_VNDK_USE_CORE_VARIANT.
Test: With the corresponding change in build/make, remove libbinder
      from build/soong/cc/config/vndk.go and check build fails even
      when TARGET_VNDK_USE_CORE_VARIANT is not set.

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For an outdated reference on Android.mk files, see build-system.html.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