Cleanup formcalc method generationchromium/3427
This CL simplifies the FormCalc method call generation when converted to JavaScript. Currently we output the same chunk of code to run the given method on an array or object per method call. This CL pulls out the common execution code to a pfm_method_runner function which is used instead. An embedder test has been added to verify that method invocation from formcalc works correctly.
