Xe3p hardware prefetches memory ranges and notifies software via an
additional bit (bit 11) in the page fault descriptor that the fault
was caused by prefetch.

Patch 1 adds a dedicated stats counter to track invalid prefetch
pagefaults separately from regular faults.

Patch 2 implements the prefetch support by extracting the prefetch bit
from the fault descriptor and echoing it in the response (bit 6) only
when handling fails. This prevents CAT errors for prefetch faults.
For failed prefetch faults, a single-line error message with the prefetch
bit value is printed to reduce excessive logging.

Based on original patches by Brian Welty and Priyanka Dandamudi.

v3:
 - Split stats counter into separate patch (Matt Brost)
 - Drop xe_guc_pagefault_types.h rename patch (Matt Brost)
 - Move prefetch check to caller of xe_pagefault_print (Matt Brost)
 - Rename XE3P_PFD_PREFETCH/PFR_PREFETCH to remove XE3P_ prefix,
   add comments about Xe3+ platform support (Matt Brost)
 - Rename PREFETCH_PAGEFAULT_COUNT to INVALID_PREFETCH_PAGEFAULT_COUNT
   for clarity (Matt Brost)
 - Include prefetch bit value in error message (Matt Brost)

v2:
 - Initial implementation combining all changes
