_protos: Regenerated protos for artifact proto update

Added low_diversity_meta and high_diversity_meta artifact.proto.

These two fields represent detatched metadata files in which we can
store artifact metadata which does not pertain directly to the artifact's
cache key and as such should not stored directly on the proto itself.

The low diversity data is meant to maximize on deduplication of data
in the CAS store, while data which is expected to diverge more should
be stored in the high diversity metadata.

Also added the strict key to the proto.

The strict key is interesting to have when instantiating an Element
from a downloaded artifact, and also provides some context as to
whether the downloaded artifact's strong key matches it's strict key.
