[roll] Roll fuchsia [ui][input-pipeline] gestures: enable drag recognizer

Enable the drag recognizer, by adding it to the set of
recognizers instantiated by `gesture_arena::make_input_handler`.

Along the way, rename `one_finger_drag::Contender` to
`one_finger_drag::InitialContender`, to match the naming
in other recognizers.

Note: after I release the touchpad button, the selected
text is no longer highlighted. I'll file a separate bug
to improve that.

Original-Bug: None
Test: manual

Manual test
-----------
1. Opened an article in Wikipedia.
2. Pointed at a word.
3. Pressed touchpad down with one finger.
4. Moved finger until pointer was at end of sentence.
5. Saw that the text from the initial word to the end of the
   sentence was highlighted.
