Remove unused proto import for LayerTreeHost.

Remove unused proto import for LayerTreeHost.

The initial commit of the layer_tree_host.proto
https://codereview.chromium.org/1519293002 included an unused
import for layer_tree_settings.proto, since LayerTreeHost message
does not refer to LayerTreeSettings.

The LayerTreeSettings are instead used for the
CompositorMessageToImpl messages and specifically the
InitializeImpl message.

This CL just removes the unused import to clean up code and remove
build spam.
