Merge to XFA: One test runner to rule them all.

This CL takes the three test runners (corpus, javascript, pixel) and combines
the code into a single test_runner file. Each of the individual runners still
exists and calls the test runner with their data directory.

With this change, the pixel and javascript test will now run in parallel if
multiple processors are available.
