Revert of input[type=text]: Add a workaround to fix vertical position of Noto Sans CJK 1.004. (patchset #1 id:40001 of https://codereview.chromium.org/1387783003/ )

Reason for revert:
Caused a regression on github, crbug.com/539858

Original issue's description:
> input[type=text]: Add a workaround to fix vertical position of Noto Sans CJK 1.004.
>
> If an input element has the following style,
>  - line-height: Npx
>  - FontMetrics::height(): M (where M > N)
>
> |line-height| for innerEditor was removed, and the innerEditor
> and the input content box were aligned at the top edge.  So, the
> bottom part of the text was clipped if |height| is specified and
> it's smaller than FontMetrics::height().
>
> This behavior is required because all browsers ignore
> |line-height| if |height| is not specified.
>
> Typically an error of author style causes this
> situation. However, with Noto Sans 1.004, FontMetrics::height()
> is larger than font-size, and the bottom part of text was clipped
> even if <input style="font-size:16px; line-height:16px;
> height:16px;">.  Authors don't expect this behavior.
>
> This CL updates the code so that we don't remove |line-height|
> from innerEditor if |height| is specified.  This centers
> innerEditor vertically.
