fuzzing NEW refactor harness to enable LLVM LibFuzzer and more granular fuzzing
Refactor the harness to call LLVMFuzzerTestOneInput when using
AFL, and simultaneously enable standalone fuzzing with LibFuzzer,
which disables the main function of the harness, and uses
LLVMFuzzerTestOneInput directly.
