Jiyong Park 44cf1a7779 add exclude_shared_libs for vendor_available:true libs
Adding a mechanism to conditionally exclude some shared library
dependencies when a lib is built for vendors.

Without this, some libraries cannot be earily marked as vendor_available
if they are depending on shared libs can shouldn't be marked as
vendor_available.

By using exclude_shared_libs with exclude_srcs (or __ANDROID_VNDK__
macro), we can eliminate the unnecessary dependency for vendors.

Bug: 62471389
Test: build
