[webaudio] Migrate ctor-convolver.html from audit.js

This change migrates WebAudio tests from the custom audit.js framework
to the W3C-standard testharness.js specifically targeting dir
third_party/blink/web_tests/external/wpt/webaudio/the-audio-api
/the-convolvernode-interface/ctor-convolver.html, supporting Chromium's
ongoing effort to deprecate audit.js in favor of a more consistent
testing approach.

The following test files have been updated:

• ctor-convolver.html
