anv: add a new NO_LOCAL_MEM allocation flag
We found a perf regression with
9027c5df4c51b ("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.
