[Intel-gfx] [RFC] tests/gem_bo_resize: New test to test gem object resize

From: "Siluvery, Arun" <arun.siluvery at intel.com>
Add new case to test gem object resize implementation.
The current test creates two objects, one of them is resizeable.
Before resize it is filled with data from source object using GPU blt.
Object is resized and then filled the new space with different set of data.
The content is compared against source to determine validity of new pages.
The resize ioctl implementation itself is not complete.
This test succeeds if the resized space is filled using GEM_PWRITE but it
is failing if GPU blt commands are used.
