samples/native-lib: Add an example to use wamr API from native lib (#1649)

Browse Source 
Real world native libs likely need to access the wasm_runtime_xxx API.
This example demonstrates it.

Build vmlib as a shared lib to make it straightforward to share a
single runtime instance between iwasm and native libs.
