[PATCH 2/4] drm/xe/xe_gt_pagefault: Migrate pagefault struct to header

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

Migrate the pagefault struct from xe_gt_pagefault.c to the
xe_gt_pagefault.h header file, along with the associated enum values.

Additionally, add string declarations for the associated enum values, as
well as functions that translate from the enum values to their string
counterparts.  The string variants will be useful for debugging later.
