<pre>[Win][Direct2D] Add initial Pattern handling implementation
https://bugs.webkit.org/show_bug.cgi?id=163270
Reviewed by Simon Fraser.
Provide an implemenation of Patterns for Direct2D.
No new tests. Covered by fast/borders/border-image-01.html and others.
* platform/graphics/GraphicsContext.h:
* platform/graphics/Pattern.h: Add D2D definitions.
* platform/graphics/win/GraphicsContextDirect2D.cpp:
(WebCore::GraphicsContext::solidStrokeBrush): Use a more generic return type.
(WebCore::GraphicsContext::solidFillBrush): Ditto.
(WebCore::GraphicsContext::patternStrokeBrush): Added.
(WebCore::GraphicsContext::patternFillBrush): Added.
(WebCore::GraphicsContext::drawPattern): Provide D2D implementation.
(WebCore::GraphicsContext::applyStrokePattern): Ditto.
(WebCore::GraphicsContext::applyFillPattern): Ditto.
(WebCore::GraphicsContext::drawPath): Use stroke pattern if available.
(WebCore::GraphicsContext::fillPath): Use fill pattern if available.
(WebCore::GraphicsContext::strokePath): Use stroke pattern if available.
(WebCore::GraphicsContext::fillRect): Use fill pattern if available.
* platform/graphics/win/GraphicsContextPlatformPrivateDirect2D.h:
