Merge 130513 - [chromium] Only inflate the height of rows in a popup menu when a touch device is detected.

Reviewed by Adam Barth.

Enforces a minimum row height for popup menus when a touch device is
detected.  In a previous patch (r127597), the sizing of popup was
consolidated for touch and non-touch.  Based on user feedback, reverting
to the old behavior for non-touch and only adding padding for touch
devices seems like a much safer strategy.  This patch is not a direct
revert of r127567 since the padding previously used for touch is a bit
excessive.

Covered by existing tests.
