Add validations on the `Src1` blend factors against fragment output

This patch adds all the validations on the blend factors that use `Src1`
against fragment shader outputs:
1. When any of the blend factor uses `Src1`, `blend_src(1)` must be
   declared on one of the fragment shader outputs
2. When any of the blend factor uses the alpha channel of the `Src1`, the
   fragment shader output with `blend_src(1)` must have an alpha channel.
