Convert HDR video frames to SDR when drawing to canvas

Reviewed by Jer Noble.

Core Animation has a bug with accelerated rendering where drawing an
image with HDR color space metadata does not correctly tone map the
image. To work around this, we perform our own color space conversion of
the image to the destination color space in this case.

By using CGIOSurfaceContextGetSurface, we limit this workaround to
CGContexts that are backed by an IOSurface (and so use accelerated
drawing).

Doing this color space conversion inside
GraphicsContextCG::drawNativeImage means that we'll do it each time the
image is drawn. Ideally this would only be done once for a given
{ CGImage, DestinationColorSpace } pair.
