Add agx_white, agx_contrast and HDR support to the AgX tonemapper.

Browse source 
Also optimize all tonemappers to perform less calculations per-pixel.

Note: unlike `white`, `agx_white` is limited to a minimum of `2.0` and defaults to `16.29`. When using a RGB10A2 render buffer, `agx_white` will be ignored and a value of `2.0` will be used instead to ensure good behavior on the Mobile renderer.
