Consolidate `style::Layer` properties API

The `style::Layer` class now exposes all the properties contained at `style::LayerImpl`.
This allowed to drop `style::Layer::accept()` method usage, avoid the repeated generated code
and thus save some binary size.

This patch is a part of the layers modularization effort.
