Allow javascript unit tests using webui test_api framework.

I moved javascript2webui.js over to chrome/test/base/js2gtest.js and shared it
across webui and unit tests with an extra parameter for test type, which governs
the few differences, such as what to include/subclass from and the flavor of
gtest (TEST_F v. IN_PROC_BROWSER_TEST_F).

v8_unit_test implemented 2 main methods to make it work with the generated C++
- AddLibrary - loads the file in the test context
- RunJavascriptF - launches the runTest with the testFixture and testName,
coordinating with Error and ChromeSend to report results.

Helper functions:
- Error - watches for console.error, noting failure if seen.
- ChromeSend - pulls apart the result from the test_api's call to
chrome.send('testResult', [ok, msg])
