Improve clustering of restricted_location for mojo pipes. Currently mojo pipes have three different paths to call a mojo interface, however when attributing jank we don't really worry about the mojo path, but rather who triggered mojo to execute. So modify mojo based names to group them into one for attribution. Also we expose avg_vsync_interval so that when we are computing sums over the data we can filter out events less then avg_vsync_interval since we've found that they can be very frequent. However we don't just filter them out in this metric because this metric is the ground truth and our tagging query adds conditions about what we car about.
