HDR images: Propagate headroom to gpu::raster::RasterDecoderImpl

HDR images have their tonemapping "baked in" during image decode.
This means that if the HDR headroom changes (which it does), we have
to re-decode the image. This also significantly complicates the
implementation of the dynamic-range-limit CSS property.

Fix this situation by having the tonemapping be applied at raster
time, on the service side.

In order to perform tonemapping, the RasterDecoder needs to know the
HDR headroom. Plumb that information through the following path:
- cc::TileManager::CreateRasterTask
  - already has the parameter)
- cc::RasterSource::PlaybackSettings
  - add new member)
- gpu::raster::RasterInterface::BeginRasterCHROMIUM
- (command buffer glue)
- gpu::raster::RasterDecoderImpl::DoBeginRasterCHROMIUM

In the next patch, this will be used to apply tonemapping on the
service side.

Add tests for the client side of the propagation. End-to-end testing
will require the tonemapping change (which will be in the next patch).
