cc: Move command-line and platform-specific settings.

The cc/ directory should not be reading the command line for settings
since different embedders in the same process may want to use different
settings.

This moves any logic to change settings based on the command line or
platform out to RenderWidgetCompositor in content/ so that they will
only apply to the renderer compositor.

The ui compositor already provides its desired settings on the
LayerTreeSettings object it passes to cc/.

The command-line flag settings set by WebLayerTreeViewImpl are no longer
needed as only settings that can be changed by DRT need to be there, and
those are provided via the WebLayerTreeView::Settings struct.
