drm/xe/xe_bo_move: Enhance xe_bo_move trace

Browse Source 
Enhanced xe_bo_move trace to be more readable.
It will help to show the migration details.
Src and dst details.

v2: Modify trace_xe_bo_move(), it takes the integer mem_type
rather than a string.
Make mem_type_to_name() extern, it will be used by trace.(Thomas)

v3: Move mem_type_to_name() to xe_bo.[ch] (Thomas, Matt)

v4: Add device details to reduce ambiquity related to vram0/vram1. (Oak)

v5: Rename mem_type_to_name to xe_mem_type_to_name. (Thomas)

v6: Optimised code to use xe_bo_device(__entry->bo). (Thomas)
