Plugin Power Saver Tiny: Fix Plugin.PowerSaver.PeripheralHeuristic UMA

Previously, it counted every status query. As we implemented PPS tiny,
the number of queries for tiny plugins increased, but we didn't
enforce that it was only recorded once.

This CL enforces that only the initial decision for a plugin is
recorded. It also migrates the UMA to a
Plugin.PowerSaver.PeripheralHeuristicInitialDecision name to prevent
further confusion.

This is complicated because there are three paths a plugin may follow:

1. Essential origin case. No placeholder, no throttler - Record
   immediately, in PowerSaverInfo.

2. Placeholder spawned first (because PPS tiny or background tab or
   prerendering) - Don't record in PowerSaverInfo. Record in
   LoadablePluginPlaceholder after size known. If a Throttler is
   spawned from the placeholder, tell it to not record.

3. Throttler spawned first - Record in the throttler.

Once PPS Tiny is launched 100%, case #3 can be eliminated.

Thanks all. I'm not merging the second patch since it's pretty huge.
