[Cairo] Implement ShareableBitmap::paint() with scale factor

[Daniel Bates]

Implement the scale factor variant of ShareableBitmap::paint(). One such usage of this variant is in changeset <http://trac.webkit.org/changeset/91085>. In particular, the change to Source/WebKit2/UIProcess/FindIndicator.cpp.

For completeness, the scale factor variant of ShareableBitmap::paint() was added to the CG port in <http://trac.webkit.org/changeset/90198>.

[Daniel Bates]

The WinCairo Debug build fails to compile because this variant of ShareableBitmap::paint() wasn't implemented for Cairo at the time changeset 91085 <http://trac.webkit.org/changeset/91085> landed:
