Historically, all SLRUs were addressed by transaction IDs, but that hasn't been true for a long time. However, the error message on I/O error still always talked about accessing a transaction ID. This commit adds a callback that allows subsystems to construct their own error messages, which can then correctly refer to a transaction ID, multixid or whatever else is used to address the particular SLRU.
