Review request: fix issue 7253 - tooltip of Pure English tab title has wrong directionality

This CL fix issue 7253 -- tooltip of pure English tab title has wrong directionality.
(http://crbug.com/7253)

Fix: LTR tooltip text need to be marked with LRE-PDF to be displayed correctly in RTL locales.

Test steps:
1. Open Chrome in RTL locales.
2. Open page http://mail.yahoo.com, whose title is "Yahoo! Mail: the best web-based mail!"
3. Mouse over to the tab title to show the completed page title.

Without the fix, tooltip text is: "!Yahoo! Mail: the best web-based mail" (with wrong placement of the ending punctuation).

With the fix, tooltip text is: "Yahoo! Mail: the best web-based mail!"
