Merge glTF scene rendering sample (#744)

Browse source 
* Started reworking the scene rendering to sample
Use glTF instead of ASSIMP, per-material pipelines, material loading, etc.

* Visibility toggle for scene nodes

* Fixed lighting, updated GLSL and HLSL shaders

* Renamed sample

* Code-Cleanup, comments, validation fixes

* Android build

* Started on tutorial for glTF scene rendering sample

* Minor code cleanup

* Adding new chapters to the tutorial for glTF scene rendering sample

* Added info on normal map shader bindings, spelling

* Added drawing chapter

* Getter for texture descriptors

Makes code a easier to read

* Renamed glTF scene sample

* Add markdown files to projects

* Updated readme, separate chapter for glTF samples

* Comments

* Removed unused screenshot
