Supports VNDK APEX with different versions 

Older VNDK libraries are provided as vndk_prebuilt_shared modules. Those
are added to corresponding VNDK APEX as dependencies.

With VNDK APEX installed, VNDK libs are unnecessary. By the way, since
there can be vendor modules which depend on VNDK libs, Make targets are
still emitted with UNINSTALLABLE=true.

Android.mk has additional modules for vndk libraries which are named
with apex name as suffices. For example, if libfoo is a vndk library,
then libfoo.vendor is its vendor variant and it would be in
/system/lib/vndk. But with vndk apex, it has additional
libfoo.com.android.vndk.current variant.

Bug: 141451661
Bug: 139772411
Test: m (soong tests)
Test: boot with aosp_arm64 system image on Q vendor device
