effects: Drop WindowPaintData.shader property

Browse source 
It allows us to encapsulate SurfaceItem rendering. It's needed to add
support for YUV->RGB conversion fallback path.

Effects that use this property must be ported to OffscreenEffect, see
also OffscreenEffect::setShader().

This is a BREAKING CHANGE!
