Add check between color state format and fragment shader output

This patch adds the validation on the compatibility between the format
of the color states and the fragment shader output when we create a
render pipeline state object as is required in Vulkan (Vulkan SPEC
Chapter 14.3 "Fragment Output Interface"):
"if the type of the values written by the fragment shader do not match
the format of the corresponding color attachment, the resulting values
are undefined for those components".
