mesa/st: add per sample shading state to fp key and set interpolation
This enables a gallium driver not to care about the semantics of
ARB_sample_shading vs ARB_gpu_shader5 sample attributes. When
ARB_sample_shading-style sample shading is enabled, all of the fp inputs
are marked for interpolation at the sample location.
