Per the HTML-AAM spec, section 4.1.1, certain text field inputs have a specific accessible name calculation. That computation specifies that the client should first check the control's title attribute before checking the control's placeholder value. This revision adjusts the code such that we check the title first, then the placeholder; we were previously doing the reverse. This revision also removes the expected failures from the relevant web platform test meta file. Differential Revision: https://phabricator.services.mozilla.com/D201877
