Converts layout.css.devPixelsPerPx to a static pref. This one was one of the slightly odd ones; some values were expecting an atomic float, so instead of defining a regular type float it is defined in StaticPrefList.yaml as an AtomicFloat. I am assuming this was the intent of the pref value all along.

This is the most important part of the patch series. It removes the
PScreenManager protocol and use ScreenManager directly in the content
processes.
Initial and subsequent updates are sent via PContent::RefreshScreens.
struct ScreenDetails are kept to serialize Screen over IPC.
nsIScreenManager::ScreenForNativeWidget is removed because
nsIWidget::GetWidgetScreen can replace it. nsIScreen::GetId is removed
because it's not useful for the more general Screen class.

ScreenManager takes the common parts of ScreenManagerWin,
ScreenManagerGtk and ScreenManagerCocoa. It caches all screen
information in the new Screen class. The cache are updated when the OS
notifies there is a monitor config change; all changes will be pushed to
content processes via PContent (patch part 6.)
Screen is a pure data object. All platform dependent logic will be in
widget specific helper classes.
Each process will have a singleton ScreenManager object. Widget
specific helper object is held alive by the ScreenManager when
necessary, for example to receive updates from the OS.
The change to to VsyncDispatcher.cpp is due to unified-build bustage.
ScreenManager::ScreenForNativeWidget is not implemented because it
will be removed in patch part 6.
