refactor(bar): Split GLS and raw layer-shell implementations
Extract two surface implementations from the bar class: GLSSurfaceImpl and RawSurfaceImpl. This change allowed to remove _all_ surface type conditionals and significantly simplify the Bar code. The change also applies PImpl pattern to the Bar, allowing to remove some headers and fields from `bar.hpp`.pull/892/head
