Reviewed by Don Olmstead.

WebPageProxy and API::HitTestResult objects were leaking after
270308 at main. It was caused by a cyclic referencing between
WebPageProxy::m_lastMouseMoveHitTestResult and
API::HitTestResult::m_page.

m_lastMouseMoveHitTestResult is used only if PLATFORM(MAC).

* Source/WebKit/UIProcess/WebPageProxy.cpp:
* Source/WebKit/UIProcess/WebPageProxy.h:
Conditioned out the code of m_lastMouseMoveHitTestResult with #if PLATFORM(MAC).
