Enhance wasm loading with LoadArgs and support module names (#3265)

- Add new API wasm_runtime_load_ex() in wasm_export.h
  and wasm_module_new_ex in wasm_c_api.h
- Put aot_create_perf_map() into a separated file aot_perf_map.c
- In perf.map, function names include user specified module name
- Enhance the script to help flamegraph generations
