When ENABLE_OVERVIEW_ACTIONS flag is enabled, swiping up from the nav
bar goes to overview if you hold, or the first home screen if you don't.
- Added NoButtonNavBarToOverviewTouchController, which extends
FlingAndHoldTouchController but only works if you start from the nav
bar. Otherwise it falls back to PortraitStatesTouchController to
handle normal state transition to all apps.
- Added HintState. This is where the workspace/hotseat/qsb scale down
when you swipe up from the nav bar, to hint that you're about to
either go to overview or the first home screen.
- Added getQsbScaleAndTranslation() to allow Overview and Hint states
to treat it as part of the hotseat.
- Since Overview needs to show above the QSB as it's animating, bring
Overview to the front and update OverviewScrim to handle the case
where there's no view above Overview to draw the scrim beneath.
- ENABLE_OVERVIEW_ACTIONS is always false in 2-button mode, since the
shelf is crucial to that mode.

- Add NoButtonQuickSwitchTouchController which uses
BothAxesSwipeDetector to track horizontal and vertical motion.
- Initially, we only detect swipe left to right to quick switch
(like before), but then we allow swipe up to either go to
overview (if you hold) or back home (if you don't hold).
- xDisplacement transitions non-overview components out (e.g. shelf
and workspace), and translates overview in.
- yDisplacement translates overview up and scales it down

Calling scrollToPosition on RecyclerView internally calls
requestLayout() (to cacluate where to scroll and then go there).
Therefore, we should avoid calling that whenever possible, especially
during transitions. In particular, we can optimize scrollToTop() to not
scrollToPosition() if we are already at the top.
This makes some other workarounds unnecessary, namely setting All Apps
to GONE during system gestures.
Test: Open an app, swipe up, ensure AllAppsRecyclerView doesn't get
onLayout(). If we had scrolled to an app first, we get one layout
in prepareRecentsUi(), but not during the transition.

We already set the all apps content visibility = GONE at the start of
the gesture to prevent relayouts, but when animating home we were
inadvertently changing it to INVISIBLE, causing a relayout and jank.

Now floating headers get 2 interpolators: one for the header content
itselt, and one for the all apps content that follows. That way, they
can choose to intperolate part of their content as if it were part of
all apps instead of the header. Currently, we do this to animate
predicted icons quickly, followed by the all apps icons, predictions
text, all apps scrollbar, and all apps divider as you continue swiping.

- Refactor some basic scrim logic to Scrim class and have
WorkspaceAndHotseatScrim and OverviewScrim extend it
- Draw OverviewScrim under recents unless predictions are disabled, in
which case draw it under hotseat (since that is in recents)

peeking

- Peek in overview further, and with more overshoot
- Fade out and scale down workspace faster while swiping up
- Scale and translate workspace slower when letting go to enter
overview (so it doesn't zoom out at warp speed)

We did this already for mCurrentShift, which is used for all animations
except home animation. Now we do it for the home animation as well to
ensure we are properly cleaned up for the next interaction.
Test: Swipe up to home and double tap nav region before animation
finishes. Before, this would return to the app you swiped up from but
was in a broken state where subsequent swipes were ignored. Now we
jump to the home screen and remain there.

Add AnimationComponents.ATOMIC_OVERVIEW_PEEK_COMPONENT, and rename
previous ATOMIC_COMPONENT to ATOMIC_OVERVIEW_SCALE_COMPONENT.
When SWIPE_HOME is enabled:
- Overview lives to the left of Workspace, which is encoded in
LauncherState.NORMAL.getOverviewScaleAndTranslation().
- Create atomic animation based on ATOMIC_OVERVIEW_PEEK_COMPONENT
and OVERVIEW_PEEK state when swiping and holding from home screen.

animation, so it doesn't conflict with existing state transitions.

* changes:
Remove redundant resumeLastTaskForQuickstep() and use resumeLastTask() directly
Fix some state issues with home and quick switch gestures
Apply spring forces to animate to the final position for swipe home
We only send onAnimationEnd() if both object animator and spring animator have
ended. However, we also initialized mSpringEnded = false to begin with, which
meant we would never send onAnimationEnd() if the spring animator was never
started. Now we treat the animators as ended until they are started.
Example test:
0: Enable SWIPE_HOME and QUICKSTEP_SPRINGS flags
1: Swipe up and hold on home to go to overview
2: Tap outside overview to go home
3. Swipe up to all apps
4. Swipe down
Expected: animates to home, not overview. Before this change, however, it went
to overview because the state manager never got onAnimationEnd() and therefore
never set the last stable state to NORMAL instead of OVERVIEW.

Now instead of an incorrect hack that simulated accelerating to the target,
we actually apply spring forces to make it feel realistic and work no matter
where the target is.
Added two helper classes for this:
- FlingSpringAnim handles the fling, applying friction until reaching the target,
then a spring to pull towards the final position (also applies if fling wasn't
in the right direction or strong enough to reach the target).
- RectFSpringAnim uses 2 FlingSpringAnims (x + y) to animate from a starting rect
to a target rect. It also has an animation to scale from the start rect to the
target rect, sending progress update callbacks to the caller.

* Listeners weren't getting called properly. We add one listener to the
SpringbjectAnimator and then use that to dispatch to the other listeners.
* We fast finish on both double swipe cases to prevent the shelf from
ending in an invalid state. This causes a visual jump but this can be
addressed in follow up CL.

Previously we were comparing the controller's progress at the time of
the end of the animation... which is always 1. Instead, we should be
comparing the effective final progress based on the interpolator.

creating FirstFrameAnimatorHelper on demand for individual animations.
