Fix RTL UI extension popup anchoring.

Fix RTL UI extension popup anchoring.

BubbleDelegateView::CreateNonClientFrameView mirrors in RTL.
(arrow horizontal positions/anchoring are flipped in RTL UI)
BrowserActionsContainer::ShowPopup should not do the same.
See before and after pictures at http://crbug.com/150696

BUG=150696
TEST=RTL (--lang=he) UI browser/page action extension popups should be anchored at the top left and shouldn't be cut off.
