Enable setting running mode when executing a wasm bytecode file - Four running modes are supported: interpreter, fast-jit, llvm-jit and multi-tier-jit - Add APIs to set/get the default running mode of the runtime - Add APIs to set/get the running mode of a wasm module instance - Add running mode options for iwasm command line tool And add size/opt level options for LLVM JIT
