Stefano Stabellini 4c1cd02acb xen/x86: introduce MCE_NONFATAL

Today, checking for non-fatal MCE errors on AMD is very invasive: it
involves a periodic timer interrupting the physical CPU execution at
regular intervals. Moreover, when the timer fires, the handler sends an
IPI to all physical CPUs.

Both these actions are disruptive in terms of latency and deterministic
execution times for real-time workloads. They might miss a deadline due
to one of these IPIs. Make it possible to disable non-fatal MCE errors
checking with a new Kconfig option (MCE_NONFATAL).
