commit 623d492210f53775d50dc67bee193fb1142ae726

Adds skeleton for IntentPickerAutoDisplayService

IntentPickerAutoDisplayService is a KeyedService (including a factory
class) so intent picker UI can locally (i.e. within Chrome) check if
such UI has been displayed before without the user taking action.

The user ignoring the UI should be remembered, so we stop
auto-displaying the UI and instead only show an entry icon in the
omnibox, where the UI will be one-click away.
