anv: Fill PAT fields in Xe KMD gem_create and vm_bind uAPIs

Browse Source 
Unlike i915, Xe KMD needs the cache parameter in gem_create
then during vm bind it request the PAT index that matches previous
parameter.
The PAT index selected could have more memory caracteristics that KMD
don't need to know.
