Fixes Issue 7377: Regression: Omnibox trims URL ending with 0x85

To fix this issue, this change adds a new function TrimWhitespaceUTF8(), which trims space characters (including non-printable characters and broken UTF-8 characters) from either end of a UTF-8 string.
Please feel free to give me your comments since I'm not sure this implimentation is correct. (Maybe this implementation trims too aggressively.)
