tests/gem_media_vme: Simple test to exercise the VME block

Simple test which exercises the VME fixed function block.

v2: (Tvrtko Ursulin)
 * Small cleanups like copyright date, tabs, remove unused bits.

v3: (Tony Ye)
 * Added curbe data entry for dst surface.
 * Read the dst surface after the VME kernel being executed.

v4: (Tony Ye)
 * Added the media_vme.gxa kernel source code and compile instructions.

v5: (Tvrtko Ursulin)
 * Added hang detector.

v6: (Tvrtko Ursulin)
 * Replace gem_read with gem_sync. (Chris Wilson)
