Exposing actions from the PIP InputConsumer to accessibility,
stripping all actions from a covered PIP app, and adding the
InputConsumer's actions on the PIP app's root view.
We were also using an "undefined" accessibility ID to mean
three different things: a root view, a host view of a virtual
view hierarchy, and a truly undefined view. I've introduced
new values for cases where the id could be defined.
Also gathering all window IDs into one place to reduce the
chance of collisions.

Categories were added to accessibility service info objects so that they can be grouped
in system Settings. Services can declare a category in their accessibility manifest file,
and if no category is defined, the service is placed under the "Other services" category.

Two methods on AccessibilityService were declared abstract, but
there doesn't seem to be a good reason for them to be abstract, as
it's possible to write an accessibility service that doesn't do
anything useful with the methods. Removing the abstract qualifier
to reduce boilerplate for service developers.

This allows an AccessibilityService to set a flag in its
AccessibilityServiceInfo that triggers the navigation bar to show an
Accessibility Button and observe callbacks when the button is clicked
or there are changes in the visibility of the navigation bar.

We're adding a dedicated volume level for accessibility. Services
can use the new flag to request that this volume be activated for
accessibility usages.
To let AudioManager know when the request state changes, adding a
hidden convenience method to check if any active service requests
the a11y volume stream. This method can be used to enable the
stream and to decide when to show the UI to change its volume.
AudioManager wanted a listener for changes to this flag, so rather
than add yet another special-purpose listener, I've added one that
gets called back whenever there are state changes in a11y services.
These changes happen infrequently enough that we shouldn't need
more targeted methods.

Test: Steps:
- Retrieve root AccessibilityNodeInfo

that TextView, and ensure that it's updated to reflect the text
change

Services that declare that they can control magnification,
but never actually make a change or register a listener
waste cycles as we compute magnification data they never use.
Avoid registering for magnification callbacks unless magnification
gestures are enabled, a service is listening for magnification
changes, or a service has changed magnification.

This API was using a oneway aidl call, which meant that the
service was disabled some time after the method returned. That
confused tests that were turning a service off during tearDown
and then turning it back on again in setUp.

Clarifying region used for magnification as "magnificationRegion",
both in the public API and in the code. There's been significant
confusion about what "magnfifiedRegion" means. Removing
"availableRegion" from everywhere except where it's required, as
that region was identical to magnified/magnification region.
Trying to shut down magnification was a complex situation where
animations in progress and new magnification requests were tricky to
handle correctly. It was not possible to guarantee that the
magnification callbacks were unregistered consistently. There were
at least two situations that led to phone restarts:
1. If a triple tap was detected between unregistering the callbacks
and shutting down the input filter. In this case the magnification
request would go through.
2. If an animation had just started when magnification was turned
off, so the current magnification was 1.0 but the animator was
about to change it. In this case the callbacks would be unregistered,
and then the animator would start changing the magnification.
This change makes registering and unregistering magnification atomic.
It also makes MagnificationController stick around indefinitely once it
is created, registering and unregistering as needed to support
magnification gestures and services that control magnification. Services
that merely query the status of magnification no longer register for
callbacks.
One part of shutting down is turning off the animation and guaranteeing
that it won't try to make further changes. Adding a flag to
SpecAnimationBridge and a lock in that class so we can guarantee that
nothing happens when we aren't registered for magnification callbacks.
Also reconfiguring all accessibility options when a service stops to
make sure that only the features required by the current configuration
are enabled.

Gestures now operate on the screen as the user sees it, so they are
affected by magnification. This makes gesture coordinates consistent
with the node bounds in screen and makes an eye or head tracking service
work much more easily.

Look for both EA and non-EA accessibility services, but when the user
is locked only bind to EA services. Once the user is unlocked, we
take another pass and bind to any non-EA services.
We only consider disabling accessibility once the user is unlocked,
since there could be non-EA services waiting in the wings.

Closing two small holes in the implementation:
1. The gesture was dispatched before the callback was registered. It
was possible for gestures that failed quickly to fail to report any
status.
2. Gestures could be dispatched before the input filter was
installed. Adding a wait to give the filter a chance to install
before reporting a failure.
Also removing an unused method on the input filter.
