perfetto-ui: Preperation for adding counter details

A couple of preparatory changes for adding details for counters:

- Fix a bug where drag_gesture_handler missed out of window mouseup
  and ended up in a bad state.
- Optimise counter rendering for the common case where counter value does
  not change.
- Highlight location of data point on counter track.
- Add a resizeable details window.
