drm/xe/bo: Add purgeable shrinker state helpers
Encapsulate TTM purgeable flag updates and shrinker page accounting
into helper functions to prevent desynchronization between the TTM
tt->purgeable flag and the shrinker's page bucket counters.
Without these helpers, direct manipulation of xe_ttm_tt->purgeable
risks forgetting to update the corresponding shrinker counters,
leading to incorrect memory pressure calculations.
Update purgeable BO state to PURGED after successful shrinker purge
for DONTNEED BOs.
