Add an API to terminate instance (#2538)

Browse Source 
Add API wasm_runtime_terminate to terminate a module instance
by setting "terminated by user" exception to the module instance.

And update the product-mini of posix platforms.

Note: this doesn't work for some situations like blocking system calls.
