AX: @aria-label attribute should work on <label> element

[Nan Wang]

In case:
<label for="txtBox1" aria-label="Enter date in format MM/DD/YY">Date:</label>
<input id="txtBox1" />

I would expect the value specified in the aria-label attribute to supersede the actual value of the label. I.e. I would expect VoiceOver to announce "Enter date in format MM/DD/YY". Instead the base value is announced ("Date").

this comment seems unnecessary, since its self evident from the code

const AtomicString& ariaLabel

announced by "a" screenrea
