anv: add a new NO_LOCAL_MEM allocation flag

Lionel Landwerlin requested to merge llandwerlin/mesa:review/anv-reduce-local-mem-usage into main

We found a perf regression with 9027c5df ("anv: remove the LOCAL_MEM allocation bit") which seems to be that we over subscribe local memory, leading i915 to swap things in/out too much.

This change avoid putting buffers in local memory if they are not allocated from a DEVICE_LOCAL heap.

Maybe we can revisit this later if i915 is better able to deal with more buffers in local memory.
