[client] Document the remote-jobs MDM keys in the policy schemas

Add allowRemoteJobs (bool) and debugBundleUploadURL (string) to the
remaining MDM policy schema artifacts so administrators can enforce them
through every supported channel: the Windows ADMX/ADML templates, the
macOS .mobileconfig and the bare-plist helper, and the .reg example. The
macOS managed-preferences plist was covered with the code change.
