Add GrFragmentProcessor::Compose for composing two processors.

This is functionally equivalent to RunInSeries, but the implementation
can be simpler, because it doesn't support an arbitrary number of
processors.

In practice, Ganesh no longer calls RunInSeries with more than two
inputs at once, so all existing calls to RunInSeries have been replaced
with Compose.
