The two NativeViewAccessibilityWin methods should be put back where they were to
match the .h. 

 - Create() can stay where it was too (in which case update AuraLinux), or
 - Create() can stay down here (in which case update Mac) :)

Took the first option to match what they were originally like. Sorry, I checked
them out from my old branch before edits and didn't think about whether the
reorders still made sense, but it should be good now.
