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)

+Step1: Building IGA (Intel Graphics Assembler)
+========================================================================
+
+1. Download or clone IGC (Intel Graphics Compiler)
+
+   https://github.com/intel/intel-graphics-compiler.git
+
+2. Chdir into 'intel-graphics-compiler' (or any other workspace folder of choice)
+
+   It should read the following folder strucutre:
+
+   workspace
+      |- visa
+      |- IGC
+      |- inc
+      |- 3d
+      |- skuwa
+
+3. Chdir into IGA sub-component
+
+   cd visa/iga
+
+4. Create build directory
+
+    mkdir build
+
+5. Change into build directory
+
+    cd build
+
+6. Run cmake
+
+   cmake ../
+
+7. Run make to build IGA project
+
+   make
+
+8. Get the output executable "iga64" in IGAExe folder
+
+   usage: ./iga64 OPTIONS ARGS
+   where OPTIONS:
+     -h     --help                     shows help on an option
+     -d     --disassemble              disassembles the input file
+     -a     --assemble                 assembles the input file
+     -n     --numeric-labels           use numeric labels
+     -p     --platform        DEVICE   specifies the platform (e.g. "GEN9")
+     -o     --output          FILE     specifies the output file
+
+   EXAMPLES:
+   ./iga64  file.gxa  -p=11 -a  -o file.krn
+
+Step2: Building ASM code
+========================================================================
+1. Command line to convert asm code to binary:
+
+   iga64 media_vme.gxa -p=11 -a -o media_vme.krn
+
+2. Pad 128 bytes zeros to the kernel:
+
+   dd if=/dev/zero bs=1 count=128 >> media_vme.krn
+
+3. Generate hexdump:
+
+   hexdump -v  -e '4/4 "0x%08x " "\n"' media_vme.krn > media_vme.hex
