Add BackButtonAlphaHandler to set back button alpha, instead of setting
it from multiple places.
Also force back button alpha to be 1 if swipe up is disabled (b/80091187)

Back button changes opacity when moving the shelf during swipe up
between home screen and overview. The alpha changes depending on the
progress of the swipe up animation. When going from app to home and vice
versa, the fade animation does not tie with the swipe up progress. The
fade animation also masks the back button drawable when ime visibility
changes.

Test: swipe up from home screen to overview
- Don't update the animation to go from 0 to 1; instead, update the
interpolator to clamp to the remaining progress (b/79773309)
- Fix NPE that can happen in a race between the atomic animation
ending and the non-atomic animation canceling/ending

When we enter overview (overview appears, workspace disappears):
- Workspace scales down from 1f to .8f with OvershootInterpolator(1.2f) at 200 ms
- Workspace fades from 1f to 0 with OvershootInterpolator(1.2f) at 200 ms
- Overview scales down from 1.33f to 1f with OvershootInterpolator(1.2f) at 200 ms
- Overview fades from 0 to 1f with OvershootInterpolator(1.2f) at 200 ms
When we exit overview (overview disappears, workspace appears):
- Workspace scales up from .92f to .1f with DecelerateInterpolator() at 200 ms
- Workspace fades from 0 to 1f with AccelerateInterpolator() at 200 ms
- Overview scales up from 1f to 1.1f with AccelerateInterpolator() at 180ms
- Overview fades from 1f to 0 with DecelerateInterpolator(1.7f) at 200 ms
Parallax while the finger moves: Workspace translates half the distance as the shelf

There are 3 places we can block a fling:
- Swiping from home to all apps (through overview)
- Swiping from an app to all apps (through overview)
- Dismissing a task (in the same gesture that started by swiping down)
In all of these cases, we block the fling when crossing the threshold
to a new state (e.g. OVERVIEW), but unblock if the user pauses their
drag. With this change, the logic is consistent:
- Unblock the fling after pausing a short amount of time
- If a fling was blocked, increase the settling duration based on
velocity

Previously we were ending the atomic animation with the assumption
that it should be complete/almost complete by the time you drag to
the next state. However, it is very easy to drag quickly enough where
that assumption doesn't hold, and thus you just see the atomic
animation pop to the end (i.e. recents showing without animation).
Now instead of ending the atomic animation, we let it continue. But
because the new state animation will have an atomic component that
interferes with the still playing atomic animation, we have to
control the atomic component separately; we control the non-atomic
components until the atomic animation ends, at which point we create
a separate controller to control the atomic components.

State handlers can now specify atomic and non-atomic components of
their animations to states, which can be specified when creating a
new animation. There is now one atomic animation, when going from
NORMAL to OVERVIEW (and in reverse):
- RecentsViewStateController's animation (scale/alpha) is all atomic
- WorkspaceStateTransitionAnimation has atomic and non-atomic:
- Hotseat and workspace alpha is atomic, as is workspace scale
- Everything else (scrim, translation, qsb and drag handle alpha) is
non-atomic
- All apps progress is non-atomic
Also simplified dragging through overview; no longer pulls against you,
so we use an OvershootInterpolator when flinging instead of our custom
interpolator for the spring effect.

We manually dispatch cancel when returning to the previous state in
onDragEnd(), but could end in a bad state if getting a second,
external cancel (e.g. by pressing home). Thus, we restore the
onCancelListener after manually dispatching cancel.

This cleans up the code and ensures that the current state animation
is always initialized when we get drag events.
Also log when we pass through states.

Previously, user-controlled animations weren't properly being canceled when a
non-user-controlled animation started, e.g. when hitting home. Thus, we could
end in the wrong or inconsistent state because the user-controlled animation's
end runnable was still used. Now we add a cleanup callback for when we reset
the user-controlled animation for one that isn't user-controlled.
Also fixed a couple typos.
Tests (easier with animation durations extended):
- Swipe up and hit home before reaching overview -> land on home
- Go to overview, swipe down slightly (before threshold to go to workspace)
and let go -> return to overview without flash (recents was resetting)
- Swipe up, press home while swiping -> goes home, stops responding to drag
- Start dismissing task and hit home before it finishes (or while dragging)
-> goes home, stops responding to drag

I'm not sure how/when this case occurs (perhaps during some transition/state
change), but manually removing the floating view matches the symptoms in the
bug.

We now pass the log action (e.g. SWIPE or FLING) to the pending
animation, so that the end listener can log appropriately. This
is used when swiping down or up on a task, for example.
Bug: 73783784

Example bug:
1. Swipe up to overview and let go
2. Swipe all the way to the top of the screen, past where all apps stops
3. Swipe down
Before this change, you get reset in NORMAL state instead of OVERVIEW.
By ensuring that getTargetState() checks the drag direction before
returning a new state, we guarantee we only re-init in the case that the
state is actually changing. Otherwise it's possible to change the state
to one that is impossible, such as NORMAL when swiping up from ALL APPS.

If you're ever in overview and swipe down on the hotseat, it will launch
the focused task *unless* you entered overview from the workspace and
have not scrolled past the first task. This is a hidden state to allow
for reversibility of the swipe up from workspace.
Also moved PendingAnimation from quickstep to launcher3.
