Add bp2build converter for cc library stubs and use the stub library target of a library while linking it in APEXs.

Bug: 231322789
Test: with this CL on internal master,
1) b build --verbose_failures //vendor/google/modules/AdbdGoogle:com.google.android.adbd --config=android_x86_64
2) adb install bazel-bin/vendor/google/modules/AdbdGoogle/com.google.android.adbd.apex, and adbd is activated successfully on cuttlefish device.
3) m mts && mts-tradefed run mts-adbd, and there is no failure with cuttlefish device
4) packages/modules/adb/test_device.py, and there is no failure with cuttlefish device.
