Browse Source 
Implement the shared heap feature for interpreter, aot and llvm jit.
Add below runtime APIs:
```C
wasm_shared_heap_t
wasm_runtime_create_shared_heap(SharedHeapInitArgs *init_args);

bool
wasm_runtime_attach_shared_heap(wasm_module_inst_t module_inst,
                                wasm_shared_heap_t shared_heap);

void
wasm_runtime_detach_shared_heap(wasm_module_inst_t module_inst);

uint64_t
wasm_runtime_shared_heap_malloc(wasm_module_inst_t module_inst, uint64_t size,
                                void **p_native_addr);

void
wasm_runtime_shared_heap_free(wasm_module_inst_t module_inst, uint64_t ptr);
```

And allow wasm app to call API shared_heap_malloc and shared_heap_free:
```C
void *shared_heap_malloc(uint32_t size);
void shared_heap_free(void *ptr);
```
