drm/xe/vram: Extract buddy allocation and free helpers

Browse source

Factor out xe_ttm_vram_buddy_alloc() and xe_ttm_vram_buddy_free()
from xe_ttm_vram_mgr_new() and xe_ttm_vram_mgr_del().

These new helpers consolidate block allocation/deallocation with
visible-size tracking. This modularization makes the logic reusable by
the upcoming VRAM page offlining reservation path.

No functional change.
