Laszlo Agocs 48c3173338 Add samples property for Item.layer and ShaderEffectSource 
[ChangeLog][Qt Quick] Added the properties ShaderEffectSource.samples
and Item.layer.samples to allow requesting MSAA rendering of an item
subtree, without enabling multisampling for the entire scene.

Task-number: QTBUG-58945

Laszlo Agocs 27d23848a3 D3D12: Recursive layer support 
To avoid using the same color buffer both as a shader resource and as a
render target, recursive layers add a second render target and just play
ping-pong with them. Multisampling does not need this since rendering
happens into a MS buffer while shader access uses a separate, non-MS color
buffer.
