List of VNDK-related libs are exported to make

LL-NDK, VNDK-core, VNDK-SP libraries are exported to make as
SOONG_LLNDK_LIBRARIES, SOONG_VNDK_CORE_LIBRARIES, and
SOONG_VNDK_SAMEPROCESS_LIBRARIES. This can be used to auto-generate
ld.config.txt from a template.

Bug: 64013660
Test: BOARD_VNDK_VERSION=current m -j successful
Test: check out/soong/make_vars*.mk and look for SOONG_*_LIBRARIES
