This removes the annotation from the following tests:
browser/base/content/test/general:
- browser_bug735471.js by removing the test
- browser_clipboard.js which seems like it's not using CPOWs anyway
- browser_blockHPKP.js which is disabled and isn't using CPOWs anyway
browser/components/customizableui/test:
- browser_934951_zoom_in_toolbar.js as CPOW usage was removed in bug 962248
toolkit/components/reader/test:
- browser_readerMode_with_anchor.js as CPOW usage was already removed in bug 1492482
toolkit/content/tests/browser:
- browser_datetime_datepicker.js as CPOW usage was removed in bug 1492482
- browser_saveImageURL.js which used deprecated CPOW-only APIs that I removed in an earlier cset
It also removes all the test framework code relying on this annotation.
