Add a trace_references_from dex optimization property
Introduce a new property `trace_references_from` in the optimize block.
This field allows specifying a set of downstream targets from which to
trace references when optimizing the current target.
In practice, this requires explicit breaking of any cycles that might
occur. A follow-up effort will explore doing this dynamically and
implicitly for `libs` references onto an optimized target that
enables this feature.
Bug: 212737576
Test: m nothing
Test: go test ./java
Flag: EXEMPT bugfix
