Changes: - replaced registry keys with environment variables for cl_cache in OCL - added compiler cache helpers - implemented support for new env vars on Windows - added tests New env vars mechanism works as follows: If `PERSISTENT_CACHE` is set, driver checks if `NEO_CACHE_DIR` is set. If `NEO_CACHE_DIR` is not set, driver uses `%LocalAppData%\NEO\neo_compiler_cache` as `cl_cache` destination folder. If `NEO_CACHE_DIR` is not set and `%LocalAppData%` path could not be obtained, compiler cache is disabled. In the current Windows implementation, special characters in the folder path are not supported. Related-To: NEO-8092 Signed-off-by: Fabian Zwolinski <fabian.zwolinski@intel.com>
