Message : Add varying packing validation for WebGL. This CL moves the varying packing from the D3D layer up to Program. This is necessary for WebGL validation, and gives us consistency for the various back-ends. There may be some additional cleanup work on the VaryingPacking class, because it does some work that is D3D- specific. WebGL requires strict varying packing. Instead of allowing success unconditionally, it's an explicit error to succeed to pack a set of varyings that the sample algorithm would fail to pack. Introduce a new packing mode option to the varying packing class to handle this different packing style, while keeping our old more relaxed packing method for ES code.
