[igt-dev] [i-g-t V4 15/46] lib/igt_draw: Pass region while building intel_buf from flink

[Bhanuprakash Modem]

From: Zbigniew Kempczyński <zbigniew.kempczynski at intel.com>

For i915 region doesn't matter but for xe we need to be more strict and
region aware. This is related to size and alignment constraints. As we
don't have information about flink buffer origin let's assume region
is vram if possible, otherwise choose system region.
