[SurfaceFlinger] Adapt min/max luminance from hardware composer.
The luminance capability of the display is very important to HDR content.
Previously, the minimum and maximum luminance were assumed as 0.0 and 500.0
respectively. This patch adapts the value returned from hardware composer and
plumbs the value to RenderEngine. If hardware composer doesn't return valid
values, 0.0 and 500.0 are still used as minimum and maximum luminance
respectively.
