md-history: Fix a search field regression caused by r410495.

The original behavior before r410495 depended on 1px margin-end specified by UA
stylesheet for -webkit-search-cancel-button. After r410495, the search field
correctly moves the cancel button to the left side.  This CL recovers the
original behavior by adding margin-end to paper-input-container.

Also, this CL removes selectors for -webkit-search-decoration and
-webkit-search-results-button from cr_toolbar_search_field.html. These pseudo
elements were removed from Blink.

This CL doesn't intent to fix other existing issues.
- We should secure space for the custom clear button at the right side, or
- We should flip the position of the custom clear button; crbug.com/638484
