If we send an Android ACCESSIBILITY_FOCUSED event because of a content
update (ie. scrolling to anchor or DOM selection changes) we should not
scroll the accessible into view. We should assume the content is being
brought into view by itself.
Testing: We already have tests to show that we scroll an accessible into
view when navigating content, testing for the inverse (that the scroll
is done by other means and NOT a11y) is very hard.

This unifies hit testing across all platforms.
It also removes one of the few remaining uses of virtual cursor change events.

This was done using the following script:
```
matchingFiles=`git grep -l accessibility_cache_enabled`
sed -i 's/StaticPrefs::accessibility_cache_enabled_AtStartup/a11y::IsCacheActive/' $matchingFiles
for f in $matchingFiles; do
usesA11yPref=
grep -q StaticPrefs::accessibility_ $f && usesA11yPref=1
hasA11yInclude=
grep -q 'nsAccessibilityService.h' $f && hasA11yInclude=1
if [ -z $usesA11yPref ] && [ -z $hasA11yInclude ]; then
sed -i 's,mozilla/StaticPrefs_accessibility.h,nsAccessibilityService.h,' $f
elif [ -z $usesA11yPref ] && [ $hasA11yInclude ]; then
sed -i '/"mozilla.StaticPrefs_accessibility.h"/d' $f
elif [ $usesA11yPref ] && [ -z $hasA11yInclude ]; then
sed -i '/"mozilla.StaticPrefs_accessibility.h"/a#include "nsAccessibilityService.h"' $f
fi
done

Actually, `NativeWeakPtr::Detach` may not release JNI ojbect immediately because
it depends on JNI object's `OnWeakNonIntrusiveDetach`i implementation.
`SessionAccessibility`'s `OnWeakNonIntrusiveDetach` implementation uses the
runnable to run on Android UI thread then disposer runs on main thread, so
if Detach is finished, JNI object isn't detached yet.
If calling `NativeWeakPtrHolder::Attach` immediately with same/recycled Java
object after `NettiveWeakPtr::Detach`, it is possible to run disposer for JNI
object by `OnWeakNonIntrusiveDetach` after Attach is finished. So it may
release newer attached object unfortunately.
So I would like to add a way to waiting for detach JNI object using
`MozPromise`.
Also, `MozPromise.h` includes `Natives.h` header (for `GeckoResult` support).
So I cannot modify inline method to use `MozPromise` due to recursive. So I
split implementation with `NativesInlines.h` as workaround.

This should fully eliminate the case where remote accessibles fail to
unregister because of the outer PresShell's lifecycle.

Also assure that unregistering an accessible removes the right one and
doesn't confuse the attached document with the detached one.
Add stderr output to Accessible::DebugPrint in Android as well.

This prevents copies and avoids the hack we have to avoid this, which
right now is using nsDependent{C,}String.
Non-virtual actors can still use `nsString` if they need to on the
receiving end.

The associated PresShell of the root doc can be used for retrieving the
SessionAccessibility. If the PresShell is about to go away, we should
unregister all the accessibles.

Remove assert for doc to be last accessible to be removed because
in a doc shutdown scenario it will be the first to be removed.

We can't use the StringBundle object off the main thread. We need to
pre-load all the strings we may use. This is a small set of roles. We
also need formatted heading levels, so we preload heading level 1 to 6.

We cannot use GeckoBundle anymore because it cannot be constructed in
the UI thread. Instead, have a set of populate methods that take
arguments and set the correct fields in the AccessibilityNodeInfo, or
its optional info objects.
These fields can be called both in the Gecko and UI thread.

This creates a clearer distinction between local pivots and remote
pivots. The former happens in the parent process and the latter happens
in the remote content process.

Since remote accessibles won't share AccessibleWrap as a base class
anymore this can't be an instance method. Move it to
SessionAccessibility, the sole consumer.
Note: ToBundle will hopefully get removed entirely once CTW is fully adopted.
