[PATCH 05/12] ras: flesh out estatus processing core

[Ahmed Tiba]

Complete the estatus core by adding the cache throttling logic, vendor
record notifier plumbing, IRQ/NMI queue handling and the processing
paths that walk CPER records. Landing the full implementation ahead of
the GHES conversion keeps the follow-on patches focused on their call
sites while leaving behaviour unchanged for existing users.
