After APZ is enabled on parent process on B2G, we should test SelectionCarets's SelectWord and Scroll begin/end behavior, and eliminated LongTapDetector and ScrollEndDetector if needed.

SelectionCarets does not receive NS_MOUSE_MOZLONGTAP after APZ was enabled on parent process. For example, if we long tap on rocket bar, no word will be selected.

Now that bug 1127066 is landed on master please check to make sure all the text selection stuff is working as expected. At the moment we have no remaining known issues with respect to text selection so if you find anything please let us know. Thanks!

We've tested long pressing to select a word, and hide/show carets at APZ scroll start/end on b2g parent process. It's great both features work as expected. Thanks!
