Add info about new libraries, new API usage, Android support (with caveats), CMake presets, contributors, original repo URL, etc. Start adding standalone pages to Doxygen docs.

`graphics::RenderContext` owns pipelines, samplers, etc: move as much as makes sense to the user side (`engine` will handle ownership, not `graphics`). Remove all uses of `View` and `CView`.
