Reland Combined test runner.

This reverts commit 7a4374583efc0c41c826122aa26c1198c8d5cc37.

Original Commit Message:

This CL revives the old CL to combine the test runners [1] which was reverted
due to failing font_size tests. I've deleted the font_size.pdf as it is not
needed and for testing. Pixel tests are either .in or .pdf files, not both.

Original description:
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.
