[Beignet] [PATCH v2 4/8] [OCL20]cl_mem_fence_flags definiton change from MACRO to enum

[xionghu.luo at intel.com]

From: Luo Xionghu <xionghu.luo at intel.com>

also add definition for memory_order and memory_scope.
v2: still use MACRO to define cl_mem_fence_flags as the value could be
combined like (CLK_GLOBAL_MEM_FENCE|CLK_LOCAL_MEM_FENCE) that the enum
not supported
v3: move the EXTENSION definition to another patch.
