Support HDR tonemapping in TextureView

This reuses the HDR tonemapping curve that was used in RenderEngine,
however display-level metadata may not be aligned. But because there are
no composition changes that can cause flicker, e.g., switching rapidly
between using a TextureView and a SurfaceView, then that should be okay.
That means that the HDR tonemapping is not as high quality as it could
be, but it is much better than before.
