Cherry pick [Android] Allow text handles to observe position of "parent" view Cherry pick of https://codereview.chromium.org/24449007/ Bug: 10892868 Bug: 10562149 Bug: 10723151 Original description: [Android] Allow text handles to observe position of "parent" view This adds the class PositionObserver. This class provides a way to listen for changes to the position of a particular view (and to query that views current position). Then, HandleView is updated to use a PositionObserver to keep its PopupWindow's position up-to-date with the logical "parent" view ( HandleView is logically a child of some other view, but has to use a PopupWindow outside of the logical parent's view hierarchy). This is similar to, and influenced by, Android's Editor.java (https://android.googlesource.com/platform/frameworks/base/+/android-4.3_r3.1/core/java/android/widget/Editor.java).
