SF: Carve out LayerCreationArgs

Move most layer creation logic outside of Layer.

Specify layer sequence id via creation args
and move ownerUid/ownerPid into the layer
creation args so we can share logic between
the existing layer class and the new server
layer state.

Add layer parent and mirror from handles
to be used with the new LayerLifecycleManager.
