Add dest-color support to the Pipeline stage.
Previously, when converting a program, the pipeline stage could assume
that an input to main() of type half4/float4 was always the input color.
This was a good assumption since the only possible inputs were
coordinates, or the input color.
This CL now recognizes that when a second float4 is passed to the main()
function, it should be a SK_DEST_COLOR_BUILTIN. This will let blend
functions pass in two colors.
ProgramToSkVM now takes a dest-color argument as well, but existing call
sites won't reference it (since they aren't for blend functions). I've
just passed the input-color a second time, since the value will never
actually be accessed.
