Reland "[ime] Migrates ImeService.ViewFocusChanged to ...focus.Controller.Notify"

This reverts commit b28fb6b2c90f0b7c1fc8cd8937cebe7ac3dd4c91.

Reason for revert: the root cause of the empty screen has been removed.
In short, the change was missing protocol routing declarations, which
have now been added.

Requires fxr/512198 to ensure Workstation does not break.

Tested:
  Verified locally and confirmed that the workstation screen is back.
