drm/xe: Expose bad VRAM pages via debugfs
Add a debugfs file "vram_bad_pages" that shows offlined and queued
VRAM pages across all tiles. Each entry displays the page frame number,
GPU page size, and status flag (R=reserved, P=pending, F=failed).
example,
cat /sys/kernel/debug/dri/0/vram_bad_pages
max_pages: 10000
0x0000000000000000 : 0x0000000000001000 : R
0x0000000000001234 : 0x0000000000001000 : P
0x0000000000080000 : 0x0000000000001000 : R ← tile 1 addr
v3(Michal):
-add kernel doc
v2(Sashikoi/Michal/Himal):
-Remove block iteration, use offline and queue list only
-Move platform check inside api
