Source/WebCore:

Introducing PageSupplement interface to attach behind-the-flag-ish
objects to Page instances.

This change aims to improve modularity of Modules/ entries. With
PageSupplement mechinary, we can eliminate ifdef conditionals from
Page.h/Page.cpp and are able to add Modules/ entries without
touching non-Module WebCore files. WebKit API classes like WebPage
can "provide" these objects dynamically during the Page setup phase.

In this change, DeviceMotionController and
DeviceOrientationController is updated to adopt PageSupplement
inteface for an illustrative purpose because they are going to
move into Modules/ shortly. Other Page associated API backing
objects also should be transformed to PageSupplement family.
