Reorder the contents in ReactAccessibilityDelegate.java to be more logical (#49735)
Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/49735 I always get confused when I open this file. One of the main reasons is the order of contents is quite random, so I decided to reorder things. I tried to find a style guide on this but the [google ones](https://google.github.io/styleguide/javaguide.html#s3.4.2-ordering-class-contents) really just say do something that is logical so... In general what I did was * All instance variables, class variables, class constants, etc. are at the top of the class * The constructor, `setDelegate`, `resetDelegate` methods are at the top of the class since these all deal with creating or destroying instances of this class * Nested enums towards the bottom of the class so they are not in the way of people trying to reason about the methods and other contents (they are quite long) * Delete random extra spaces / unneeded comments * Move some private methods to be closer to the public methods that call them Changelog: [Internal] Reviewed By: mlord93 Differential Revision: D70345882 fbshipit-source-id: a8425c7b90c5d4fbea5ee5daa3c4ff9f7f189ce5
