[Net] Drop is_connected_to_host for TCP and UDP.

The UDP method is now called `is_socket_connected` to limit confusion
with the actual host connection status which doesn't make sense in UDP.

The TCP method is completly dropped, use get_status instead.

The only one left is the WebSocketPeer one, which should be fine as is
for now.
