HDR: cc: Ensure that SDR content is 80 nits

Project Member Reported by ccameron@chromium.org, Jan 31 2017 
When in HDR mode, Windows 10 defaults non-HDR apps to 80 nits.

Ensure that SDR content, when drawn in Chrome (especially when using an HDR backbuffer), is not excessively bright.

Adjustments to brightness are easiest to make in the cc:: shader generation, so adding completion of  issue 667966  as a blocker.

Not sure how this is an issue.
As long as SDR content that output #FFFFFF gets mapped to 1.0f, 1.0f, 1.0f in the float buffer, SDR content cannot exceed 80 nits.

80 nits is pathetically low, and I'm kind of hoping that Microsoft has some support for making legacy apps more than 80 nits, but until we get answers from microsoft, just mapping non-hdr content to 1.0 in HDR space should be enough.
