Drew Davenport b29c974d70 drm_hwcomposer: Return composition decision from backend 
Rather than setting the ValidatedType on the layers directly from the
Backend, return the per-layer composition type decisions from the
Backend and let the HwcDisplay set it.

This is a step towards the goal of not setting HwcLayer state directly
from the Backend.
