Add the 'GraphicsSurface::UseLinearFilter' flag to Canvas2DLayerTizen.

[Title] Add the 'GraphicsSurface::UseLinearFilter' flag to Canvas2DLayerTizen.
[Issue] VPSS-870 TDIST-184
[Problem] The <canvas> image is distorted by minification (when its scale factor is not 1.)
[Cause] The Canvas2DLayerTizen's CanvasFlag doesn't have UseLinearFilter.
[Solution] Canvas2DLayerTizen::graphicsSurfaceFlags() returns UseLinearFilter.
