trace, ras: add ARM processor error trace event
Currently there are trace events for the various RAS errors with the exception of ARM processor type errors. Add a new trace event for such errors so that the user will know when they occur. These trace events are consistent with the ARM processor error section type defined in UEFI 2.6 spec section N.2.4.4.
