* Add View::setFrontFaceWindingInverted() API
This API can be used to flip all meshes in a render pass
inside out. This is useful for mirrored rendering.
This change also disables face culling on the default skybox
renderable. Since it is unlit, there is no downside to this
and the mesh being in the device vertex domain it can never
be backfacing unless front face winding is inverted.
* Track face winding state in Vulkan
