[core][Android][Darwin] LayerManager creates RenderLayer instances

`LayerManager` is now responsible for `RenderLayer` instances creation,
so that there is a single entry point for creating of objects, which
correspond to a certain layer type.

The `LayerType type` field is dropped from `Layer::Impl`.
