add CMake option USE_STANDALONE_GBE_COMPILER and STANDALONE_GBE_COMPILER_DIR
At some platforms with old c/c++ environment, C++11 features are not supported, it results in the failure to build the gbe compiler part which depends on LLVM/clang using C++11 features. The way to resolve is to build a standalone gbe compiler within another feasible system, and build beignet with the already built standalone gbe compiler by setting USE_STANDALONE_GBE_COMPILER=true. The path of the standalone compiler is /usr/local/lib/beignet as default or could be specified by STANDALONE_GBE_COMPILER_DIR. Once USE_STANDALONE_GBE_COMPILER is given, all the gbe compiler relative code will not be built any longer, only libcl.so and libgebinterp.so are built. And libcl.so is special for GEN_PCI_ID, which is queried from the building machie or could be specified as CMake option. v2: separate the CMake option name. update the commit comments. add back the script for gen pci id, and build driver with it. v3: add file FindStandaloneGbeCompiler.cmake to make the main cmakefile clean.
