ElementTiming: move tests to WPT This CL moves Element Timing tests from http/tests to external/wpt. The php files used are rewritten in python. Some of the images used are copied over because the sizes/types sometimes matters. supported-element-type.any.js is removed: it was invalid format before, now it's redundant with supported-element-type.html, and we do not want workers to have 'element' in supportedEntryTypes.
