TaskbarScrimViewController was previously unaware of visibility
changes that happened to taskbar outside of when the sysui state
flags changed. Additionally, isTaskbarVisibileAndNotStashing is not
a reliable signal as the visibility might be GONE even though taskbar
is about to animate to be visible (i.e. shade is showing and then
you swipe it back up -- taskbar scrim wouldn't appear because when
the sysuiStateFlags changed, taskbar visibility would still be 'gone'
at that point so the taskbar scrim wouldn't animate back when
the shade is swiped up).
To resolve this, I've added a callback to notify the scrim
controller of visibility changes and it'll update if needed.
Bug: 270634233
Test: manual - enable 3 button nav
- have a bubble
- go to overview
- expand bubbles
=> observe that scrim appears over taskbar
- swipe down shade
=> observe that scrim fades out
- swipe shade up
=> observe that scrim fades in

- Roundness will be 0 in Launcher, and 1 in an app
Bug: 250645563
Test: With and without taskbar in overview, switch between home/overview/app and observe the round corners above taskbar
Test: Ensure corner above taskbar is correct in overview and in app when chat bubble is active

Test: stash and unstash taskbar, background drawn as before; open a
Bubble and ensure taskbar is still scrimmed

When bubbles are expanded a scrim is shown on top of
everything. Taskbar is layered above bubbles but we still
need the scrim to show on top of it. This CL adds the
ability to show a scrim on taskbar.
The scrim is a view in the taskbar drag layer and is
placed between the taskbar and the nav buttons so that
it can block touches / scrim the taskbar but still allow
the nav buttons to be visible and touchable.
Add interpolators for alpha matching what bubbles is using.
Test: manual 1 - expand bubbles while taskbar is visible
=> observe scrim
- open manage menu
=> observe darker scrim
2 - check that taps on scrim collapse manage
menu or stack
3 - check there isn't a scrim while taskbar is
stashed and bubbles / manage menu are open
4 - check that three button nav works while
bubbles are expanded
