This is part 1 of implemeting phantom windows for the window controls when using --ash-enable-alternate-caption-button

Other notable changes:
- Switched to using layer animations instead of gfx::SlideAnimation
- Renamed PhantomWindowController::phantom_widget_ and PhantomWindowController::phantom_widget_start_ to PhantomWindowController::phantom_widget_in_target_root_ and PhantomWindowController::phantom_widget_in_start_root_ respectively.
- Removed PhantomWindowController::Hide(). Hiding the phantom window can now only be done via destroying the PhantomWindowController

Added memory and V8 metrics to indexeddb_perf results

We are trying to deprecate the page_cycler.indexeddb performance test.
One of the things done by that test and not indexeddb_perf is the
measurement of V8 memory statistics. This change brings V8 stats
into indexeddb_perf - but only a subset of the full measurements.
Opted for a smaller subset as the full set has too much unrelated
stuff, and we really want to catch things like unreleased objects,
etc.
