Autofill seems to need IDs to be preserved across things
like configuration changes, while accessibility will not
function without views with unique ids. Separating out the
two types of IDs. We can re-combine them once it's clear
that both demands can be satisfied.

There are some apps that use the Surface object itself to indicate
changes. As a result, recycling the existing Surface object for
updates can lead to such apps ignoring events such as size changes.
This changelist restores the original behavior for legacy apps, where
the underlying native Surface object is recreated during updates.

Test: Open affected application, observe expansion to fullscreen when
nav bar disappears. Rotate to other orientation and observe
expansion to fullscreen.

- Unify logic for detecting availability of the accessibility button
- Ensure the initial visibility state is propagated to A11yMS
- Ensure services only receive availability callbacks for changes

Let's first understand how mView could become null. Notice
at the beginning of performTraversals, there is a check that
mView != null, and so it is nulled while we are in the function.
mView is package private and there are only two places which assign
to it, ViewRootImpl#setView and ViewRootImpl#doDie. setView is guarded
by mView == null. But mView was not null (per the check at the beginning
of performTraversals) and so mView is being nulled by doDie().
doDie() only has 3 callpoints:
1. ViewRootImpl#die(). Here though, calling it is guarded by
!mIsInTraversal. !mIsInTraversal is unconditionally set at the
beginning of performTraversals, and so this isn't our caller.
2. ViewRootHandler, handling MSG_DIE. This runs on the same thread
as performTraversal, and so it can't be our nuller.
3. WindowManagerGlobal#addView. This must be our nuller.
We see WindowManagerGlobal#addView will call doDie in the case that
we attempt to add a view which we had previously set to be removed
but deferred removal of. Now we can construct a reasonable sequence
for getting here:
1. requestLayout(). Perform traversals ends up on handler.
2. removeView(). MSG_DIE ends up on handler, View ends up in mDyingViews
3. performTraversals is executed by the handler
4. From a callback initiated by performTraversals (e.g. measure)
the client calls WindowManagerGlobal#addView on the view which
was just removed.
5. We are still in performTraversals so MSG_DIE hasn't been processed
yet. This means that WindowManagerGlobal will perform the doDie
immediately nulling mView.
6. We return to performTraversals and crash.
We can see shortly after the offending call to doDie, a new ViewRoot will be
constructed and so whatever traversal we are doing on the old one doesn't
seem particularly important. It doesn't seem that we can do any better
than letting it fall through without crashing.

we force RenderThread over to use async mode which
we enable via eglSwapInterval(0)

This CL will be reverted once it merges into the next release branch
to re-introduce the proposed APIs.
This CL also makes the following code changes to preserve API
compatibility:
-- It keeps the recently added RemoteViews.clone() synchronized logic
intact, but moves it inside the method to avoid changing the API
signature.
-- It reverts the RttCall.read() behavior to the oc-dev logic, since
we can't throw IOException until we get an API level bump. (The
original logic returned null instead of throwing.)
