Bug: 62862624
Test: Enable magnification, then enable TalkBack with the
a11y shortcut. Verify that volume keys work.
A11y service CTS, a11y units tests.

Only filter a11y motion events if needed.
We've seen some jitter in motion events with accessibility
enabled. We can eliminate it by not passing motion events
through the filter if we know they won't be affected.

Fix a11y key event handling from multiple devices.
For M, we ignored device type entirely, but with ag/760625 we started
paying attention to it, which rejects events when keys from different
devices are pressed simultaneously. Since the volume keys show up as
different devices, the new behavior disrupted the event stream when
both volume keys were pressed.
Now tracking each device separately, which restores the old behavior
but still takes the device id into account. Holding down two keys
when enabling an accessibility service, however, always has and still
can produce an invalid event stream. It doesn't seem worth the
overhead, however, to track each key separately.

Treat accessibility gestures like physical ones.
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.

Protect MotionEvent stream when a11y changes.
I found this hole while looking for a solution to a bug when
magnification was enabled when TalkBack was running. I believe
what was happening was that enabling/disabling magnification
resets the AccessibilityInputFilter. The filter batches MotionEvents
for processing with a choreographer, but the disable/enable cycle
when magnification gets enabled could disrupt the event stream.
This change flushes the batched events before objects using them
are disabled.
I've tried a variety of things, but I'm not able to reproduce the
bug on NYC using the same procedure. I suspect that either the
timing of the events is different, or the newer gesture detection
in TalkBack is protecting it somehow. The hole remains, though,
and could create invalid streams of MotionEvents without this fix.

Clean up accessibility gestures.
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.

Always reload AccessibiiltyInputFilter on user switch
Makes AccessibiilityInputFilter aware of current user ID, and pasess the
user ID to event stream filters that have per-user parameters:
- AutoclickController -> for per-user autoclick delay
- ScreenMagnifier -> for magnification scale
While doing this, make AccessibilityInputFilter.disableFeatures private,
and replace usage in AccessibilityManagerService with
setUserAndEnabledFeatures with feature flags set to 0:
Using disableFatures directly leaves input filter in inconsistent state
where internal mEnabledFeatures flags don't match real state of enabled
features.

Feed mouse and keyboard events to EventStreamTransformation
Updates AccessibilityInputFilter to pass keyboard and mouse events
through enabed EventStreamTransformations.
This is done in preparation for implementing Autoclick on mouse stop
feature, which depends on those events.
Existing EventStreamTransformation implementstions are modified to
non touchscreen motion events and key board events.
Adds stub EventStreamTransformation (AutoclickController) that will
be used to implement autoclick feature.
Implements key event filtering as a separate EventStreamTransformation
(instead of doing it directly in AccessibilityInputFilter).
Introduces private EventStreamState classes to AccessibilityInputFilter,
which keep track of whether event sequences for different input sources
have started, and help reduce code duplication when determining whether
an event should be fed to registered EventStreamTransformers.
