drm/xe: Implement print vfunc for page fault info logging

Add a print vfunc to xe_pagefault_ops so different producer backends can
log specific relevant debug info while keeping the consumer layer free
of potential backend-specific formatting logic.

Consumer-specific error prints are handled by passing as input into
the vfunc.

v2:
 - Decode producer specific fields for print message. (Matthew)
 - Combine consumer and producer prints to one print call. (Sashiko)

v3:
 - Change assert to WARN_ON_ONCE. (Matthew)
