Define ViewMsg_ColorProfile IPC message and plumb it into renderer
RenderWidget::SetDeviceColorProfile(). The browser uses the IPC to
set the renderers screen color profile.

Note SetDeviceColorProfile is overridden by RenderViewImpl, so the
IPC message data is handled there - it calls the base RenderWidget
SetDeviceColorProfile, which detects if the color profile changed,
and stores it in the RenderWidget if so.

If there was a change, the RenderViewImpl informs its webview() so
the Page contained therein can update / repaint all color profiled
elements on the Page.

For a diagram of the IPC and procedure call proceedings, including
layout test support (added in issue 369787), see:

Not used as yet: the IPC from the browser-side will be added later
(need to resolve issue 338130, issue 357443 first), so this change
is again just plumbing.
