Move LayerSorter to exist locally only in layer_tree_host_common

Move LayerSorter to exist locally only in layer_tree_host_common

At this time, LayerSorter does not need to be owned by the layer_tree_host_impl
and passed into calculateDrawProperties. This patch moves it to
layer_tree_host_common.cpp, and removes any leftovers from other files.
