[Impeller] A toolkit for managed handles to Android NDK vended objects.

[chinmaygarde]

Only available on Android device API levels >= 29. Proc table is setup has versioning checks. All handles are type safe. Collection of handles takes into account cleanup tasks (like reparenting surface controls). The proc table contains code duplicated in ndk_helpers and I will remove that in favor of this in a subsequent patch.

Part of https://github.com/flutter/engine/pull/51213 being chopped up.
