Allow converting the zero wasm address to native (#3215)

Browse Source 
This allows to know the beginning of the wasm address space. At the moment
to achieve that, we need to apply a `hack wasm_runtime_addr_app_to_native(X)-X`
to get the beginning of WASM memory in the nativ code, but I don't see a good
reason why not to allow zero address as a parameter value for this function.
