feat: replace CreateHTTPRequest with CreateHTTPRequestScriptVM

Allows the game client to make HTTP API calls from a listen server
(local lobby) instead of requiring a Steam dedicated server.
CreateHTTPRequestScriptVM has the exact same API signature but works
in both dedicated server and listen server contexts.
