Implement extension cl_intel_device_side_avc_motion_estimation.

This patch mainly contains:
1. built-in function __gen_ocl_ime implementation.
2. Lots of built-in functions of cl_intel_device_side_avc_motion_estimation
   are implemented.
3. This extension is required to run in simd16 mode.

v2: move the utests to seprate patches one by one;
    as all the utests has extension function check, no need to put them
    in stand alone utest;
    uncomment the self test;
    fix extension check logic issue, should be && instead of ||.
