[Android] Horizontal drag events aren't delivered to a platform view (webview) in TabBarView #147425

Split out from https://github.com/flutter/flutter/issues/134420.

Based on that issue, it seems that horizontal drag events on a webview nested inside of a TabBarView are not delivered to the platform view, allowing the webview to scroll as expected. See https://github.com/flutter/flutter/issues/134420 for a reproduction and an example of this behavior.

Possibly related to vertical drag events not being delivered to webviews in scroll views: https://github.com/flutter/flutter/issues/146570
