Subject : [perf] Change google.com to google.co.uk in top_10_mobile_memory and dual_browser page sets.
Author  : mythria
Commit description:
  
In the top10_mobile page set google.com gets redirected to google.ca. This
sometimes causes problems in telemetry with scrolling. As a short term fix,
replace google.com with google.co.uk in the page set. We cannot change it
to google.ca because memory_top_10_mobile uses the same page set but with
a different wpr that has a recording of google.co.uk. Updated dual_browser
page set to be consistent with top_10_mobile page set.

Also recorded new wprs for memory_top_10_mobile, dual_browser and
top_10_mobile_memory.
