Summary: After facebook#2570, `mountDepth` is only used to enforce that `setProps` and `replaceProps` is only invoked on the top-level component. This replaces `mountDepth` with a simpler `isTopLevel` boolean set by `ReactMount` which reduces the surface area of the internal API and removes the need to thread `mountDepth` throughout React core. Reviewers: @sebmarkbage @zpao Test Plan: Ran unit tests successfully: ``` npm run jest ```

Is it safe here to assume that this is going to be a ReactCompositeComponent?
Edit: Otherwise, preventExtension will complain. 👎

Yea, it's because the callback is used with a "context". Annoying OO pattern.
Edit: This will probably change but it's currently true.
