When upstream ioctl helper is created it will try to create small
allocation, adding I915_GEM_CREATE_EXT_SET_PAT extension. If it
succeeds, for all resources with valid pat index value it will then
explicitly program pat index value with gem create ext call.
PrintBOCreateDestroyResult value can be used to:
- print whether the set pat extension is supported by the kernel, when
ioctl helper is created
- print whether set pat extension was added for a given gem create ext
call and what pat index value was programmed
Note: introduced changes are disabled by defualt.
Toggle DisableGemCreateExtSetPat can be used to enable new functionality.

In some of the drm functions there is a pattern
to store array in unique_ptr and pass it's length
as an argument. This commit simplifies this.

Use structs defined in ioctl_helper.h instead of
i915 dependent ones to avoid conflicts between
different kernels
