[WinCairo] REGRESSION(r280726): registry keys enabling GPU process mode don't work

r270175 (Bug 219294) added registry keys to enable GPU process for WinCairo port.
But after r280726 (Bug 228803) changed the function name, they don't work.

1. Set the registry
   reg add HKEY_CURRENT_USER\Software\WebKit /v gpu_process_canvas_rendering /t REG_DWORD /d 1 /f
2. Start WinCairo WK2 MiniBrowser
3. Go to a web page containing 2D canvas. For example, http://www.kevs3d.co.uk/dev/canvasmark/
4. Start Windows Task Manager and check if WebKitGPUProcess.exe is spawned
