Fix the bug of the hide key on Omnibox.

Fix the bug of the hide key on Omnibox.

Fix a bug of hide key where the keyboard does now show up after the hide key is
pressed while Omnibox has the focus and Omnibox is touched.
I changed the way of retrieving the text input type to use
InputMethod::GetTextInputType rather than TextInputClient::GetTextInputType
because NULL is always set to touch_pressed_handler when omnibox is touched.
I also added code to check the touch event type so that the notification is sent
only when text element is touched.

BUG=none
TEST=manually

Peng is in the process of refactoring how the keyboard visibility is controlled.
 I've added him as a reviewer here.
