CPER records describing a firmware-first error are identified by GUID.
The ghes driver currently logs, but ignores any unknown CPER records.
This prevents describing errors that can't be represented by a standard
entry, that would otherwise allow a driver to recover from an error.
The UEFI spec calls these 'Non-standard Section Body' (N.2.3 of
version 2.8).
Add a notifier chain for these non-standard/vendor-records. Callers
must identify their type of records by GUID.
Record data is copied to memory from the ghes_estatus_pool to allow
us to keep it until after the notifier has run.
