Browser+WebContent+WebDriver: Move Get All Cookies to WebContent

There are a couple changes here from the existing Get All Cookies
implementation.

1. Previously, WebDriver actually returned *all* cookies in the cookie
   jar. The spec dictates that we only return cookies that match the
   document's URL. Specifically, it calls out that we must run just the
   first step of RFC 6265 section 5.4 to perform domain matching.

   This change adds a special mode to our implementation of that section
   to skip the remaining steps.

2. We now fill in the SameSite cookie attribute when serializing the
   cookie to JSON (this was a trival FIXME that didn't get picked up
   when SameSite was implemented).
