drm/xe: Add helper to extend CPU-mirrored VMA range for merge
Introduce xe_vm_find_cpu_addr_mirror_vma_range(), which computes an
extended range around a given range by including adjacent VMAs that are
CPU-address-mirrored and have default memory attributes. This helper is
useful for determining mergeable range without performing the actual merge.
v2
- Add assert
- Move unmap check to this patch
v3
- Decrease offset to check by SZ_4K to avoid wrong vma return in fast
lookup path
v4
- *start should be >= SZ_4K (Matt)
