Facebook: Add cannot create cookie error page.

- Added a cannot create error page for circumstances that prevent us from creating cookies for users.
- We only re-direct to this error page if we encounter a situation where we may need cookies to function properly.
- Added an authorize filter hook to control when the redirection occurs.
- Added a configuration value to make the no cookies error page act similarly to the existing error page.
Facebook: Test functionality of OnCannotCreateCookies hook.

- Added tests to validate flow, triggering, and default behaviors.
Update NormalizeImageFormat to support x-icon mime type for images.
