Bug 1878358: Fix accessible name calculation for text field inputs, r=Jamie

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.
