drm/xe: Drop bo->size

bo->size is redundant because the base GEM object already has a size
field with the same value. Drop bo->size and use the base GEM object’s
size instead. While at it, introduce xe_bo_size() to abstract the BO
size.

v2:
- Fix typo in kernel doc (Ashutosh)
- Fix kunit (CI)
- Fix line wrap (Checkpatch)
v3:
- Fix sriov build (CI)
v4:
- Fix display build (CI)
