Used by the engine to run a console command's callback function. This will only be called for commands that were added with AddConsoleCommand, which concommand.Add calls internally. An error is sent to the player's chat if no callback is found.
This will still be called for concommands removed with concommand.Remove but will return false.
trueif the console command with the given name exists, and
falseif it doesn't.
