UnifiedPDF: Implement initial support for dynamic content scaling
https://bugs.webkit.org/show_bug.cgi?id=287623
rdar://144775149
Reviewed by Abrar Rahman Protyasha, Tim Horton, and Simon Fraser.
Add PlatformCALayerClient::platformCALayerDynamicContentScalingDisplayList(),
a function to override when the layer contents provides the dynamic
content scaling display lists in explicit fashion.
Implement this for tiled layers that provide the PDF content through
AsyncPDFRenderer. Map the platform layer to a particular tile in a tile
grid, and map that tile into rendered PDF content. Make the PDF content,
RenderedPDFTile, to hold the DCS display list.
Generate the DCS display list by calling the PDF drawing code twice:
once with a bitmap-backed ImageBuffer, once with DCS display list
-backed ImageBuffer. The bifurcated ImageBuffer would not work, as
the PDF drawing uses the underlying platform context that is not
bifurcated.
