hwc: Fix bugs with mixed mode MDP comp
Fix reseting on handles, they never were in most cases,
owing to wrong size.
Fix redrawing, which needs to be done also when the fb's zorder changes.
Fix mdpcount update which should happen before we assess the pipes
available versus the pipes needed.
Handle video only cases, where other UI layers could be present, but we
cannot use MDP comp for them.
Restructure MDP comp decision model and some redesign.
