Sample code extends existing create-massive-size subtest to run
on multi-GPUs boards. This will currently work only with
--drivers or IGT_DRIVERS options selecting at least two dGPU
cards.
v2: Fixed bug in opening wrong multi-gpu device (Zbigniew)
v3: revert to use filter count, add require for xe, change
subtest description
v4: correct description
