Add vendor variant of libtextclassifier_hash_static for libneuralnetworks_common

I'm trying to switch all NNAPI libraries to use the libtextclassifier_hash_static.
Otherwise, Soong sees both libtextclassifier_hash & libtextclassifier_hash_static as
com.android.neualnetworks dependencies, while we need only need one,
the static variant.

Test: build crosshatch & flashed device.
