drm/xe/vma: Modify new_vma to accept struct xe_vma_mem_attr as parameter

Browse Source 
This change simplifies the logic by ensuring that remapped previous or
next VMAs are created with the same memory attributes as the original VMA.
By passing struct xe_vma_mem_attr as a parameter, we maintain consistency
in memory attributes.

-v2
 *dst = *src (Matthew Brost)

-v3 (Matthew Brost)
 Drop unnecessary helper
 pass attr ptr as input to new_vma and vma_create
