Separate SkVM's SampleChild into two callbacks.

Previously, one callback was used and the caller needed to infer from
the passed-in index what type of effect to invoke, and which arguments
were valid.

Now, each type of effect has a separate callback with a unique
signature. (In particular, SkColorFilters lack coordinates entirely.)
In a later CL, SkBlenders will also be supported, and those will have
a different signature again, as they take two colors and no coords.
