android13/test/vts/hals

The files and sub dirs under this dir contain test HAL modules that are functionally similar to the ones in the corresponding nexus device's HAL dirs but are compiled in a different way (e.g., with a post-compile-time instrumentation or direct source code instrumentation). Those instrumentations are mostly for the VTS's fuzzing and tracing-and-logging when such can't be done in a non-intrusive way.
