        [Haiku] Implement ImageBuffer support
        https://bugs.webkit.org/show_bug.cgi?id=35288

        Covered by existing tests.

        Complete implementation of ImageBuffer for Haiku. Uses StillImage
        class to export a WebCore::Image and associated GraphicsContext
        to perform arbitrary drawing in the offscreen BBitmap buffer.

        * platform/graphics/haiku/ImageBufferData.h:
        * platform/graphics/haiku/ImageBufferHaiku.cpp,
        (WebCore::ImageBufferData::ImageBufferData),
        (WebCore::ImageBufferData::~ImageBufferData),
        (WebCore::ImageBuffer::ImageBuffer),
        (WebCore::ImageBuffer::~ImageBuffer),
        (WebCore::ImageBuffer::context),
        (WebCore::ImageBuffer::image):
            Implementation uses offscreen BBitmap and BView, wraps StillImage
            around those to provide WebCore::Image interface.
        (WebCore::ImageBuffer::platformTransformColorSpace):
        (WebCore::convertFromData):
            Method just performs BGRA <-> RGBA conversion.
        (WebCore::convertFromInternalData):
            Method just performs BGRA <-> RGBA conversion and handles
            pre-multiplying the color values if requested.
        (WebCore::convertToInternalData):
            Method just performs BGRA <-> RGBA conversion and handles
            de.multiplying the color values if requested.
        (WebCore::getImageData):
            Common code for the next two methods.
        (WebCore::ImageBuffer::getUnmultipliedImageData),
        (WebCore::ImageBuffer::getPremultipliedImageData):
            Implemented.
        (WebCore::putImageData):
            Common code for the next two methods.
        (WebCore::ImageBuffer::putUnmultipliedImageData),
        (WebCore::ImageBuffer::putPremultipliedImageData):
            Implemented.
        (WebCore::ImageBuffer::toDataURL):
            Uses Haiku "Translation Kit" to convert image data to data
            of the requested mime type.
