Remove the ability to trigger the edit bookmark dialog via URL.

Remove the ability to trigger the edit bookmark dialog via URL.

In the way way back dark ages, the edit bookmark dialog was
triggered from the webui NTP by navigating to chrome://editbookmark
with the bookmark type encoded in the URL.

We have long long since moved to a native ntp and trigger it via
a direct intent, so we can remove this logic and clean up the
intent param handling to avoid invalid data.
