Open-source editions Bazel rules for embedding defaults.

These utilities provide a way to embed a FeatureSetDefaults message into generators or runtimes that need to implement feature resolution.  They use protoc to handle the tricky reflection-based algorithm over feature protos, leaving only simple merges to be implemented in other languages.  See docs/design/editions/editions-life-of-a-featureset.md for more information.
