Bug 1484157 - Add bounds check tests for WebDriver pause action. r=whimboo

The pause action takes an unsigned integer as input, but it was
discovered in https://github.com/mozilla/geckodriver/issues/1355
that chromedriver accepts floating point values.

To achieve conformance in this area, this will test various allowed and
disallowed values so that the pause action's bounds are properly checked.
