Added support for new Compiler Cache environment variables in Level Zero. Moved `opencl/source/compiler_interface/default_cache_config.cpp` `level_zero/core/source/compiler_interface/default_cache_config.cpp` to shared directory `source/compiler_interface/default_cache_config.cpp` Switched enabling cache by default from per OS to per API. Changed default state of cl_cache in Level Zero to disabled. Related-To: NEO-10045 Signed-off-by: Fabian Zwolinski <fabian.zwolinski@intel.com>
