[PATCH RFC i-g-t 0/2] helper function

[Zeng, Oak]

@Brost, Matthew This is the improved version of the igt helpers. It has some clear concepts of creating buffer and command buffer, and command submission. With those simple concepts, we are able to write an igt test in <20 LOC, see patch 2.

We might still fine tune those helpers but roughly the concept shouldn't change much. 

Do you think we can simplify existing igt tests such as xe-exec-fault-mode using those helpers? Do you suggest us to give it a try? If not, we will just use those helpers for svm test only.

The subject can be something like: Introduce helper functions for buffer creation and command submission etc
