Move most files from platform/scroll/ to core/scroll/

Most of the functionality in these files interacts closely with layout and paint, so it makes sense
to put them in core/ to eliminate needless indirection. Since there are no remaining sub-classes of
ScrollableArea outside of core/ this is mostly a mechanical refactoring.

The PlatformChromeClient class is removed here, as it is now obsolete. Previously, the only
subclasses were ChromeClient (in core/page/) and a unit testing stub in
platform/scroll/scrollbar_test_suite.h. Since scrollbar_test_suite.h has moved into core/scroll/,
it can use EmptyChromeClient (from core/loader/), just as other unit tests in core/ do.
