emulation.setUserAgentOverride

[sadym-chromium]

Specification for emulation.setUserAgentOverride command.

• Introduce a new hook "WebDriver BiDi emulated User-Agent".
• Fetch spec update required, as the default User-Agent headers is set BEFORE the "WebDriver BiDi before request sent" is invoked, so there is no way to distinguish between the user explicitly set the User-Agent vs the default User-Agent value was used. Use the hook in Fetch spec: [WebDriver BiDi] emulate user-agent string whatwg/fetch#1851
• HTML spec update required to return the proper User-Agent as the result of the navigator.userAgent. Use the hook in HTML spec: [WebDriver BiDi] emulate user-agent string whatwg/html#11576

Thanks @sadym-chromium ! Overall that looks fine to me. Just some nits and suggestions. Before approving I just want to check the reason why we attach this to the session rather than to the remote end. Back to you

@juliandescottes PTAL I believe I addressed your comments, thanks!

Oh I didn't notice that the context/contexts error was also in the other commands. Thanks for fixing them as well. Looks good to me now!
