Support automatic user prompt handing in WebDriver BiDi

[jgraham]

This reads the return value from the WebDriver BiDi user prompt opened algorithm and uses it to decide whether to show the prompt, or skip showing it but act as if it had been accepted or canceled.

At present the prompt opened function can return three values: "none", which causes the prompt to be displayed, "accept", which acts as if the prompt was accepted, and "dismiss" which acts as if the prompt was rejected. The WebDriver side is responsible for ensuring that only valid responses are sent for each prompt type (e.g. for an alert there isn't a "dismiss" option).
