    drm/xe: Add a shrinker for xe bos
    
    Rather than relying on the TTM watermark accounting add a shrinker
    for xe_bos in TT or system memory.
    
    Leverage the newly added TTM per-page shrinking and shmem backup
    support.
    
    Although xe doesn't fully support WONTNEED (purgeable) bos yet,
    introduce and add shrinker support for purgeable ttm_tts.
    
    v2:
    - Cleanups bugfixes and a KUNIT shrinker test.
    - Add writeback support, and activate if kswapd.
