Add a soong wrapper for R8's tracereferences
Add a new traceReferences rule that wraps the base R8 tracereferences
command. This allows generating a set of keep rules after tracing
references from a given set of sources onto a given target jar.
This will be used to keep hidden/unannotated members of optimzed
libraries that may be referenced by other bundled libraries on the
platform.
