Swift incremental compilation will break soon

[big-guy]

Gradle's incremental Swift compilation is based on updating the YAML file read by the swift compiler.

Expected Behavior

Incremental Swift compiler will need to rely on YAML and binary format files to work going into the future.

Current Behavior

Incremental Swift compiler relies on YAML file to force the Swift compiler to only compile files that had changed.

Context

This YAML file is being replaced by a binary format: https://twitter.com/slava_pestov/status/1271259364704256001
