Show keyboard when the focused editable field is touched inside the web content area.

When an editable fieled is touched and the focus is moved to the element, NOTIFICATION_FOCUS_CHANGED_IN_PAGE is sent. However, if the field is already focused, no notification is sent. But keyboard should be shown in such a case.

This CL
- Adds NOTIFICATION_FOCUSED_EDITABLE_NODE_TOUCHED notification, which is sent when the focused editable field is touched,
- Adds ChromeViewHostMsg_FocusedEditableNodeTouched IPC message, which is sent from renderer to browser when a touch released on the focused editable field,
- Changes RenderWidget to handle touch events in OnHandleInputEvent, and
- Handles NOTIFICATION_FOCUSED_EDITABLE_NODE_TOUCHED in KeyboardWidget to show keyboard.

BUG=none
TEST=Manual
