Split general scrolling tests out of scrolling_coordinator_test.cc

All tests in renderer/core/page/scrolling/scrolling_coordinator_test.cc
except for the UMA test testing ScrollingCoordinatorTest::UpdateAfterPaint
are moved into renderer/core/page/scrolling/scrolling_test.cc.

To avoid naming conflict, rename renderer/core/scroll/scrolling_test.cc
to renderer/core/scroll/scroll_test.cc.
