Roll ML Service mojoms from Chrome OS

This roll brings the removal of some workarounds for old Mojo, no longer
needed on Chrome OS side.

Mojoms rolled with:

cp ~/chromiumos/src/platform2/ml/mojom/*.mojom \
  chromeos/services/machine_learning/public/mojom/ && \
sed --in-place --regexp-extended \
  -e 's~^import "ml~import "chromeos/services/machine_learning/public~g' \
  -e 's/(GraphExecutor)& request/pending_receiver<\1> receiver/g' \
  chromeos/services/machine_learning/public/mojom/*.mojom
