Add test configs for URL display experiments

This CL adds test configs for the URL display experiment group that
launches all three URL display experiments and SafeBrowsing Delayed
Warnings.

SafeBrowsingDelayedWarnings was launched standalone for M85. In M86 and
above, it's launched with the other URL display experiments. It's also
no longer launched on Android as the URL display experiments aren't
implemented on Android.

The CL also removes a couple of obsolete configs so that the bots
don't hit the command line length limit.
