drm/xe/svm: Extend MAP range to reduce vma fragmentation
When DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR is set during VM_BIND_OP_MAP,
the mapping logic now checks adjacent cpu_addr_mirror VMAs with default
attributes and expands the mapping range accordingly. This ensures that
bo_unmap operations ideally target the same area and helps reduce
fragmentation by coalescing nearby compatible VMAs into a single mapping.
