Revert of Textarea resize-able only to larger; min-height and min-width properly set (https://codereview.chromium.org/239983004/)

Reason for revert:
Regression for RTL textareas.


Original issue's description:
> Textarea resize-able only to larger; min-height and min-width properly set
> 
> Textarea does not respect the min-height and min-width property when they are
> set by user. When textarea min-height and min-width is set by the user and
> if we resize textarea it will only resize to value larger than the width and
> heght of textarea and not with value smaller than it's width and height. It
> assumes width and height as min-width and min height and does not take into
> account the actual min-width and min-height set by user. This patch removes
> this bug by initializing the setMinimumSizeForResizing value with min-width
> and min-height.
