       Adding a hook to collect data for a Google UMA histogram to track when
       m_needsCompositedScrolling is turned on and off.

       We want to keep track of this information to quantify the effects of a
       few patches that will cause us to opt in to composited scrolling.
       Specifically, we want to measure the effects of
       https://bugs.webkit.org/show_bug.cgi?id=109302,
       https://bugs.webkit.org/show_bug.cgi?id=109966,
       https://bugs.webkit.org/show_bug.cgi?id=109591, and
       https://bugs.webkit.org/show_bug.cgi?id=107618.

       We do this by measuring a per-layer boolean value, and comparing the
       ratio between number of layers opted in and number of layers that remain
       uncomposited. We hope the relative number of layers opting in will
       increase after the relevant patches land and are enabled.

       Unfortunately implementing extra statistics is impractical at the
       moment since most of the actionable relevant data is expensive to
       compute. For example, it would be useful to know if the layers that opt
       out do so because of invisible or non-overlapping layers that cause a
       potential stacking container's children to be discontiguous, because we
       would potentially be able to mitigate the problem. However, this would
       add considerable overhead to perform overlap testing just to gather
       data.

       No new tests (no change in behaviour).
