WPT server should use its own testharness.js file and generate a warning when it does not match WebKit version

[youenn fablet]

As discussed with rniwa and bem in the past, wpt server uses WebKit testharness.js file to run the tests.
This is ok in most cases, except when syncing WPT tests.

When syncing WPT tests, one needs first to sync WebKit testharness.js to ensure that nothing wrong happens.
Then syncing WPT tests can be done.
This adds unnecessary burden to the task of syncing WPT tests, which is already complex enough.

It might be more appropriate to:
- Always use WPT version for WPT tests.
- Add a warning when WK testharness.js is not matching WPT version so that WK testharness.js gets updated.

Need to wait to land this patch as WebKit testharness timeouts are different from WPT default values.

Since everything is in WebKit, it's probably better to call it layout_test_testharnessjs_file instead.

Nit: an extra space at the beginning.
Also, this should probably be a FIXME.

I don't think this comment is necessary. Please remove it.

Nit: according WPT testharness.js.

Except for this one. I am not sure what you are suggesting.
Let me know and I'll be able to fix that as a follow-up patch.
