MDL-87258 mod_lti: request access for PNA
Since Chrome 142, public servers accessing resources on local networks gets blocked by default. Users need to allow access for such requests to proceed. This patch introduces a new config setting `ltiallowlocalnetwork`. This determines if the local-network-access flag should be added to LTI iframes so that Chrome users get prompted when a local network access is being made.
