Propagate data_bins from Soong to Make

Write the list of a test module's data_bins value to the
`LOCAL_TEST_DATA_BINS` Makefile variable defined for each module.
This enables downstream tools to correctly set up the runtime
environment for execution. And currently only sh_test, cc_tests, and
rust_tests has this attribute in Android.bp.
