Roll ML Service mojoms from Chrome OS

This roll brings in the enum value for a new Smart Dim model.

Mojoms rolled with:
cp ~/chromiumos/src/platform2/ml/mojom/*.mojom \
  chromeos/services/machine_learning/public/mojom/
sed --in-place --regexp-extended \
  's~^import "ml~import "chromeos/services/machine_learning/public~g' \
  chromeos/services/machine_learning/public/mojom/*.mojom

Then updated .cc references to renamed Mojom names.
