* Add support for WASI sockets to C API
Add support for WASI sockets in the C API by adding a new API to handle
preopening sockets for clients. This uses HashMap instead of Vec for
preopened sockets to identify if caller has called in more than once
with the same FD number. If so, then we return false so caller is given
hint that they are attempting to overwrite an already existing socket
FD.
