When an interrupt is received for correctable errors indicating that error
counter has crossed its threshold, read the current counter value and
deliver a drm-ras error-event to userspace for each affected component.

Also send drm-ras error-event to userspace for uncorrectable errors on
receiving an AER.

To avoid sending duplicate events when the same component appears multiple
times in the response, Send the error-event once per component.

Similar to threshold crossed case, we should probably have a BUILD_BUG_ON()
against XE_RAS_NUM_ERROR_ARR.
This is already added part of correctable. Seems unnecessary to add it twice
'sent' is a local variable and needs its own BUILD_BUG_ON() IMO, but
upto you.
