Ensure outputs are downloaded before sending TargetComplete event via BEP #17798
Description
Description of the feature request:
Currently, when building with --remote_download_toplevel, outputs of toplevel targets / aspects are only guaranteed downloaded before the build command exits.
However, the consumers of BEP, e.g. IDE, may listen to TargetComplete event from BEP and expect outputs are ready to be processed when the event is fired.
What underlying problem are you trying to solve with this feature?
We should wait for the downloads before sending TargetComplete event to not break the expectations for consumers of BEP.
