Remove LayoutTextControl::ComputePreferredLogicalWidths()

This function is an incomplete copy of |LayoutBlockFlow::
ComputePreferredLogicalWidths()|.  |LayoutTextControl::
ComputeIntrinsicLogicalWidths()| was a part of
ComputePreferredLogicalWidths().  When ComputeIntrinsicLocalWidths()
was added by http://crrev.com/577bff1, we should have removed
LayoutTextControl::ComputePreferredLogicalWidths().
