VR: remove the layout listener from mVrPopupContainer

Since the size is always updated using update method, the listener
is not needed. Moreover, the listener might have wrong width and
height information that can't be used for updating the buffer size.

The listener can get called during the updating the autofill
options with invalid Width() and Height() values. As a result,
buffer size would be wrong and Chrome crashes.
